Algorithms In Interviews SUCK | Prime Reacts

[@JensRoland]

Prime: “Algo interviews show that you’re wise and skilled enough to practice algos for weeks to show that you can learn something hard and won’t fight the system” Also Prime: “If Google wants to offer L69 but I have to spend two hours on a take-home test, TAKE A HIKE GOOGLE, I got four kids to name and a beautiful wife to defrag!” And there you see the problem with algo interviews: the devs who can’t be bothered to waste weeks doing leetcode aren’t always stupid or unwise contrarians; sometimes they’re busy experienced people who value their time and would rather spend those leetcode weeks on real-world valuable stuff like learning Go or burning React books.

If memorizing algorithms for coding interviews was a sign of intelligence none of the staff/senior developers would have taken the experimental jab. Sacrificing your DNA and bodily autonomy for "the greater good" is the same way these work 80 hour a week leetcoders think.

I dont agree with your last take. I've been a self taught SE working for over a decade, with different tecnologies, PHP, Java, Python, JS, and others. I consider myself more of a generalist dev, or a solutions guy, I dont depend on a specific tool, I know the fundamentals, and can easily use different tools to solve a given problem. So, you're not a script kiddy if you need to lookup something on Google syntax-like, sometimes I forgot basic shit like simple syntax "how to make a loop". Guys dont forget, the language is just a tool, youre paid to solve problems, that happens in your head not in the language.

[@computernerd8157]

As long as you dont claim to be an expert in those languages I agree. Based on what I see on job boards, companies want you to know about 5 different ones with 2 to 3 year exprience which is funny because if you jump around tech you may know more but you never feel super confident in them. I think I might want to attempt getting a job that focuses on one or two languages. The problem with the web is that they ask the world of you. I am looking more towards embedded or Games now the problem is how to get this Magical professional exprience without anybody wanting to hire you? That is the next problem I must tackle.

There is a saying between finance people. We hire math and science guys because you can teach them to do business but you can't do it the other way around. If the candidate is better at memorizing patterns in algorithms (yes, it isn't pure "memory work" like some might like to think), they are good talent and in X years will do better than the stubborn person boasting that they have X years of experience and do things fast simply because they have the muscle memory down, but can't even learn how to algorithms! LeetCode, like psychometric tests, is relevant criteria when making investment in talent. You either understand why companies do it or you don't.

We have a leetcode king on our team and nobody likes refactoring or working on their code. It's nearly impossible to read without going to him and asking because of many-decade-old programming practices like using the smallest variable names possible "to save space" on multiple-hundred gigabyte devices. You will find incredibly complicated algorithms inline in front-end code when a couple method calls from a library could perform nearly identically. His code performance is often exceptional, but it's incompatible with almost everybody. We just have him write systems that people don't often need to go back into to change.

And those business requirements *are* algorithms. Your working applications are built of algorithms. But these algorithms are high level, big and complex. You cannot ask to "translate business requirements into working applications" in a 40 minutes interview. So the only way to assess if you can do it is to ask you to construct some small and simple algorithm instead, more fit for the time scale of the interview.

[@skaroeth]

Throwing me a Leetcode algorithm problem for a web dev position and having the perception that I'm not a good dev because I couldn't remember said algorithm I think is pretty disrespectful to the dev and a waste of the interviewer's time. I think it really depends on the position if the job doesn't really ever use advanced algorithm's like web dev I don't think you are learning much by giving an algo test. Maybe if you don't care if the individual passes it and you want to see their process of thinking through a problem then it could maybe be valuable. Although I think having an assessment where the dev is having to solve a problem they would likely work on for that job is way more valuable to an interviewer and a better experience for the dev applying.

[@purdysanchez]

I've had multiple companies only give you 5 to 10 minutes to do the "algorithm" part of the interview. Others give like 45 minutes when the algorithms are difficult. All in all algorithm interview questions are sort of a lottery system. I'll give you an example. "Rotate an image 90 degrees without using any extra memory". You either are familiar with this or you aren't. If you've done it before and you remember the solution, you'll be able to complete it, but I've seen multiple FAANG developers fail this question.

[@dandogamer]

Totally agree, a lot of these challenges require knowing an unintuitive trick and sadly if you dont know the trick, you might get a solution but not an optimal one that the company wants so you likely get rejected

[@KM-zd6dq]

Totally agree, but I would agree hiring base on network is more common and more random than algo. But I see no one mentioning that

[@pratyushudhani]

I've had some really great algo interviews because a good interviewer doesn't care about if you can solve leetcode hard in 10 sec, he cares about your understanding of underlying data structures and your methodology. Being able to present your skills through projects is a plus but just understanding and solving some patterns is a good metric to judge a programmer. Cause what are we if not bug fixers and problem solvers at the end of the day.

[@robertluong3024]

I've had those too. Sadly, I didn't interview for good US tech companies. I've interviewed for crappy shop companies that think they should borrow Google questions and look down when you can't solve things quickly. It's weird. I wouldn't mind grinding algo questions for months if I got a US tech salary but I don't.

[@scvnthorpe__]

Tbh I think we should also look to high level design. Truth be told a ton of companies could best be investing in learning opportunities and skills growth on the job if knowing 10 bajillion algorithms/frameworks is required, rather than a ping pong table or some shit you're just going to lose social credit rating in management's eyes for having the gall to use anyways. At minimum dev bootcamps and companies need to communicate better on what it is that they actually need of people to start doing the fucking job. If THE industry of information systems can't figure this shit out then I'm astounded wider society hasn't collapsed from sheer failure to allocate labour and resources.

[@HeaDStrongTerran]

In my experience it just depends on the interviewer. Maybe that is why people fear them. I had interviews where I was asked to solve rather involved problems and the interviewer was responding to questions, was giving hints to me missing things and leading me along. So I could really demonstrate my skills. And then I had interviews where the interviewer asks me some trivial maybe bit gotcha question on some code snippets and then gives me a complete silent treatment. Some of them I did not immediately catch and see the problem - zero feedback. Some I explained in detail the problem and the solution only to be met with - so you think this code is good or bad? I completed the interview and immediately sent them an email that I am withdrawing my application. Remember when you interview with a company it is a two way street. You are there also to evaluate them and if you have the luxury you can dismiss weak candidate employers.

[@x0rn312]

I really like this idea of formally withdrawing your application when you have a bad experience like this, and to be clear I don't mean a bad experience where you didn't do well - I mean a bad experience that tells you this is not a company I want to work for. I think these companies would improve their hiring practices if they got that kind of feedback more often. Way to lead by example - props to you sir.

[@HeaDStrongTerran]

@@x0rn312 that's naive thinking I am afraid. I don't think companies often change their culture due to outside or internal feedback. I know companies that absolutely suck.

Your best option is just to look for red flags early and move on without a care if they improve or not.

[@Takyodor2]

I think this is the take I agree the least with in a very long time (I really liked the article). Thinking that the last paragraph is contradictory "study algorithms in your free time, it will make you a better developer" after saying "there are many ways of figuring out someones skills and suitability for a development job, that are better than checking algorithm knowledge" is beyond silly to me. There are many things that could help you become a better developer (linear algebra, set theory or category theory, reverse engineering software, and so on), but are those skills a good idea to _test for_ in an interview? No! Pretend the article was about reverse engineering instead. Pretend the last paragraph said "practice reverse engineering in your free time, it will make you a better developer", and that interviews consisted that depend on you solving a "crack-me" during the interview. How absurd is that? I'm not an employment interviewer, but if I'd been, I'd want to know how well the candidate is at 1) Communicating their thoughts while dividing a complex problem into manageable pieces 2) What they consider "good" code, maybe ask them how they would refactor something to make it more readable or more efficient (or both) 3) Check their methodology while searching for a bug (do they use the debugger/debug-prints where appropriate? how fast do they locate the broken code? what is their approach to fixing the issue, and is the fix maintainable and robust?) 4) Last, and probably least as well, I'd check that they have a basic grasp on time/space complexity and would use the most suitable data-structures and algorithms for a specific problem (maybe give a scenario, and ask them which algorithm would be best suited). I'm not saying algorithms aren't important, or that they say nothing about programming skills, but (as the article portrayed quite well in my opinion) they shouldn't take up a majority of an interview.

[@yaksher]

I feel like the problem with leaning too much on algorithms in interviews is that it just becomes a "did you put in the practice time to memorize enough algorithms patterns in typical interview questions" which doesn't really measure any particular ability to program. The problem is the same as the problem with every other heuristic: the moment you let people know what it is, they can game it. It's part of the reason colleges use such complex selection criteria and why KZbin obfuscates its recommendation algorithm: the moment you tell people what it is, it falls apart, because it's a heuristic and people can always game it. Algorithms interview type question are a useful proxy for knowledge _if they're not the standard thing everyone does,_ at which point their value becomes greatly diminished and they're no longer testing much except whether you practiced for them.

[@vitalyl1327]

It's very easy to see if the answer was memorised or invented on spot.

[@LillyAnarkitty]

Prime keeps moving the conversation away from the argument that the article is making. The article is saying that algorithmic questions shouldn’t be used in interviews; Prime keeps arguing that candidates should prepare themselves for those interviews. Edit: well that kind of got cleared up at the end Edit edit: he’s also betraying a very ignorant understanding of neurodivergence and disability. The idea that there are some people with real disabilities and they suffer a lot and we all need to feel really bad for them and give them special things and everyone else just needs to suck it up and conform to the standards of corporations is bullshit. I would encourage Prime to use some of that hard working rugged individualism and put some effort into educating himself before yelling about people he doesn’t understand on stream.

[@Slashx92]

About the second edit. I think his point is that we don’t male accommodations for people with different. We are told to just “be better”, “make a list”, “use words”, “just like everyone else” It’s a very modern thing to have a place in the office to deal with sensory overload, for example. And I think prime was referring to that, not that we are less and he is sad we are less, and we need prizes to feel better

Doing it while having people expecting me to talk about it - nope. I'm just not as performant when under social pressure. Navigating interactions requires a part of my focus which has to be diverted from, and if the outcome of interactions is more important, more focus has to be diverted, resulting in worse performance. See, you have to express your thoughts in words, you have to consider the recipient of the message and the level of their understanding, you have to not look weird, you have to be diplomatic (also consider who you are talking to), you have to watch for other peoples' reactions, you have to balance being proactive and reactive, you have to not offend someone (by being too interrupting), you may not be a pushover and maintain your personality, you have to listen to what others say and process the information. And this dynamic continually changes to which you have to adapt.

My experience: it doesn't matter if you're asking directly about alogs that much. It's important how you approach the answer part. If you just wait until the interviewee gets it right or dies from stress, you're doing it wrong. If you're more interested in having them show you their thought process and fluidity in working with a given programming language, that's great. Let them think out loud, see how they react to hints and if they can gauge the efficacy of their own solution. Let them course-correct if they get it wrong - you'll get to see how they debug and how they react to failure. Don't just throw linked lists at them, they won't ever use them.

I do think people can use that word like a cudgel which dilutes any meaning the word has. But at the same time, the outright rant against the use of the word at all made me angry. Sometimes it makes sense to use a generic term instead of getting into what autism (or whatever else) is etc…. Also, as someone with ASD, I don’t think it’s fair to make light of someone thinking and interview is high pressure, bc for me it is. It’s incredibly hard to focus and trust the interviewer. I spend so much mental energy thinking through every little detail and trade off, and the verbosity with which I talk generally is not appreciated or understood in an interview. Also, oftentimes the questions that are asked simply don’t make sense to me bc of how they are asked, and if you don’t get it right away, (in my experience) you get rejected. Things that are hard for everyone are generally just harder for me, not due to any issues with intelligence but issues with processing. Frankly it sucks, and any change to the process that makes it easier for people with a brain like mine is appreciated. It’s not an excuse to not work hard at something, but I also don’t see any issues with being vocal about how the current interview process in our industry is incompatible with certain brains.

I think technical interview problems should closely resemble the problems you would face while working at that company. Wtf would I need to do leetcode for a job that only requires CSS, for instance? I also think that the interviewer should be engaged in the interview, give clear and concise instructions, trying to help guide the candidate so they can succeed and not checking twitter or Instagram.

Most devs never build data structures. Should they? Maybe. But most don't. As such asking about data structure specifics IMO has never been a representation of a persons dev abilities.

For instance I ask why linked lists used to be a reasonable choice in the 80's/90's but not so much today.

@@boscodomingoas cache lines became longer, cache coherency became more important. Linked lists tend to lead to your data being spread across more cache lines. While linked lists can still be better in some scenarios, contiguous arrays are faster now more than they used to be because the larger cache lines benefit arrays more. You can still construct a use pattern that makes linked lists faster, but it is more often the case that the increased cost of something like deleting a middle element in an array is worth it because of the improved cache performance of iteration. Note that there are many more advanced data structures that can maintain some of the cache performance of arrays with some of the features of linked lists. Some fun ones to look into are skip lists and colony (being proposed for c++).

While I do agree with you, the social aspect is a very important factor in your ability as a software developer. Just being able to solve algorithm-style problems is already not a good indicator of how you'll do as an employee, but if you can barely communicate in an interview, that is a pretty big red flag. Software development, believe it or not, requires the ability to socialize with other people, asking questions and communicating your thoughts and ideas coherently. It will sometimes be in high-pressure situations as well. I get the struggle because I've been there (and will be interviewing again soon) so I'm not just being an ass.

So what if this "problem" required you to do triple axels (ice-skating) would you still do it? Sorry man I see your point and I do also thing that for some positions you might need to be good at solving algorithms but tbh I 've seen many developers that were great additions in teams without having to test their algorithm solving power. I really believe it's a matter of technical + soft skills something that it is not easy to find out through this type of interviews. On the other hand the interviewers unfortunately need some kind of a metric so they can be able to finally decide who to pick amongst all these many candidates, right? Edit: Man while watching this I was really thinking I wouldn't want you to be my interviewer!!! 😅😅😅

[@ScottHess]

Something to keep in mind is that a good interviewer wants to know that map of your abilities. That means they want to work towards the edges of what you can do, so after a good interview you should feel like you’ve been a bit challenged, and if you don’t feel that way it should make you question whether you want to work there in the first place. But that is only loosely correlated with hiring. Sometimes you need cheaper junior people. Sometimes the candidate was more than good enough, but you wouldn’t mind being part of the team that hired someone really amazing. You can’t figure that out by stopping halfway there.

[@ErazerPT]

Kind of on the fence here... Crux of the point being, whatever "deep ish" we're talking about, either a) someone WAY BETTER than me has already solved it and/or b) it's WAY ABOVE my skill set. So, if stuff is at "that level" I'm just the wrong candidate for that job no matter what... Practical example base on an internship i did a few years back, i can't write any paper in Arxiv regarding ML or come up with the corresponding models, i can't write Python/Tensorflow/Keras from scratch and my high school math surely isn't up to writing gradient descent. But none of that stands in the way of being capable of bringing it all together and pushing out a prototype that met the client requirements. Just because you can't make an internal combustion engine doesn't mean you can't drive a car, and just because you can doesn't make you a good driver. Horses for courses...

Not solving little problems that ultimately amount a hill of beans and all for a little dopamine hit that makes me feel good about myself. There is a point of diminishing returns when it comes to how useful studying DS&A is. And you reach that point well before the point you are ready for interviews. To me, this explains why so many juniors are so clueless when it comes to actually building software. It takes them years on the job to grasp the skills it takes to design and develop. For me, I instantly accelerated to a point where I was near senior level in 3 years. But I spent 5 years during schooling working on toy projects. I didn't even know what leetcode was until I hit the interview scene. Of course I had DS&A courses, but those only cover trivial stuff. It is vital to have DS&A in your wheelhouse. I'm not denying that. Especially understanding Big-O. But the questions they ask these days require you to have a master's in leetcode, essentially. They try to present them like they are problems you would face on the job, but it's just flattly not true.

[@EbonySeraphim]

Algorithms solving doesn't signal general development capability; it is only a likely correlated skill because it's unlikely someone will have learned to write the O(N log N) sorting algorithms if they can't write code at all. However, directly speaking solving algorithms like that only establishes a floor. A not-uncommon occurrence is for those who are more educated in math or applied math instead of computer science or software engineering; those folks tend to have weak programming and worse general development ability, and usually write code that solves complex, but small problems, with simpler and smaller data (typically numerical and sets). That is a small fraction of general development skills. At best, they also have the ability to recognize a problem described or defined in natural language (English), and map it to a math or computer science model and problem, and solve it. That part is good and very important, but still a fraction.

[@commonsensesoftware]

First, thanks @ThePrimeTime for providing multiple perspectives - both for and against. I love the approach to ask about existing work. That is one of my favorite approaches and usually makes candidates feel comfortable; after all, it's their work. Generically, algorithms in interviews are okay, but not all algorithms are created equal. It wasn't clarified in the discussion, but when I think of algorithms in interviews, it's usually along the lines of "traverse a b-tree in ascending order" or "find the optimal path in a graph". These are important things to know, but I don't find them useful or impressive in interviews. I've interviewed hundreds of people and I'm not interested if you can memorize and recite an algorithm (anymore), which IMHO is a very common occurrence for algorithm-type questions. The biggest problem with such a question isn't the pressure (etc, etc), it's that you need to solve the problem in 30 mins (usually all that's left after the non-coding part) on a whiteboard. Developers don't work on whiteboards. We have keyboards, copy, paste, and the internet. A big portion of the job is finding answers, not memorizing them. I'm far more interested in how someone thinks, which is hard to teach and even harder to change. If you do need to implement a specific algorithm, can you find the answers on your own? Can you spot the difference between the correct implementation of quick sort versus not? Are you capable of problem deconstruction and original thinking? While I empathize with the author and even agree with quite a bit of his assertions, I can't get onboard with the conclusion. Unfortunately, this is the current state of the union in the industry, but I think we can better.

For 90% of jobs out there, I would say almost any person with some basic algorithmic reasoning developed can perform well. The % of people that is really building new things is almost negligible compared with the number of total devs. Indeed, with the help of AI, those helper functions that you may typically need when doing some business logic can now be done with the help of the AI. I find these things more "romantic" than "a real requirement", in a similar fashion as someone who thinks learning C (and/or many university courses you will never ever need unless you end up in that 1% of jobs) is a must for being a developer. I can understand FANG companies make those interviews, but not the remaining 99% of companies that just copy what others do to feel "oh, we are cool too".

[@Mr-Ibee]

There's a guy who's a student in my uni's CS department. He spends so much of his time solving LeetCode questions and preparing for those interviews and he's become quite good and knowledgeable in them. However, that's where the pros for him stops. He has no external projects that he's worked on and his general coding skills are lacking. At a hackathon I was at he left his partner halfway through and started grinding out those interview questions. Yes, I 100% agree that algorithmic coding interview questions are a great test, but there's also a point where, as you noted, people need to also do more. In his case, algo questions is all he knows. If it's not writing an algorithm, he doesn't know how to do it and it's sad to think the industry has him so obsessed with trying to pass those coding interview questions that he's lost sight of all the other things that he needs to do to be a good dev.

By schema builder do you mean like; some sort of json encode/decode because I think that is the easiest way to create object? or do you mean something like a function that takes an object and a new property, and you need to insert that new property to the object returns the new object with that property? I think asking someone to make some sort of schema builder is a better way to test someone's programming knowledge or experience. But technically this is not an algorithmic interview. This is more like knowing and implementing DS So my take is 1.) I think there is a disconnect between what you are thinking and the blogger. The blogger is more like don't let someone knowledge or lack of knowledge about algorithms becomes the deciding factor to hire someone (example if someone don't know how to implement Dijkstra's algorithm). Instead, it should be something they learn on their free time or something to improve one's self. 2.) A) Is it okay to ask for algorithmic style interview. I would say Yes. But limit it to what will actually be used. B.) A person's knowledge about DS and its inner working are more important in most cases. C.) Other technical questions. (example asking someone if they can implement a recursive function based on a changing condition) PS. I'm always thinking about it, but I just confirmed today that quicksort is in-place sorting algo.

I think it is good to ask about algorithms in interviews. The only way you're getting any medium to hard algorithms question right with minimal help in a short amount of time is if you've seen it before. When you do algorithms in university, you get a week to do the problems with office hours. Interviewers expect you to do the same kinds of problems in half an hour or they go back and tell their boss you don't know basic programming. No matter how much you talk through the problem and explain your process, if you don't reach the answer that's a fail. So now there's a rush for everyone to memorize as many leetcode solutions as possible so that if you're asked something similar you can spit up the answer. So now we're not even testing algorithms, just if you do leetcode in your spare time. An interview style I like better is just asking the candidate to describe technical challenges in their last job, and judging them by how much detail they're able to go into, in addition to whiteboard coding

"Why would I want to hire someone who wants to kick against the system?" He develops systems for a living and can't answer that? If you have a system that is doing the wrong thing, as a good dev, you want to bring it up and propose to change what it does, not adapt to it and jump through its hoops like a moron. What he's saying would apply to any kind of irrelevant skill that could be tested for arbitrarily. Like literally jumping through a goddammed hoop. You just need to get good at hoop jumping if you want to get a job as a developer, it's the "secret handshake"! The point is clear I think: familiarity with a certain type of problem is being tested, and the way to obtain that familiarity is to solve that type of problem over and over again. If solving them was relevant to our job, there would be no problem, that familiarity would be there by default. And so, when it fits the position, the candidate doesn't have to practice them specifically. If instead we're having to practice them just for the interview, he's almost correct, I think if we replace "secret handshake" with "secret jerk off" in his analogy, it remains just as valid, while being more accurate about the power dynamics in place. And it also better fits the self-serving notion that there is some kind of Wall of Genius between dumb developers and those who are familiar with that particular kind of problems, which in 99% of the cases only gives them the benefit of being part of a secret jerk off circle.

With over two decades of experience, my approach to interviews is grounded in the belief that candidates who exhibit a willingness to learn and grow, even if they answer around 80% of the questions, often surpass those with impeccable answers but adhere strictly to a 9 to 5 mindset. While algorithm questions are valuable, they don't constitute my sole focus. What takes precedence is comprehending a candidate's background and its alignment with our role's prerequisites. By engaging in insightful inquiries and discussions, my aim is to unearth their problem-solving prowess, communication finesse, and cultural harmony within our organization. This method facilitates a holistic evaluation, ensuring that candidates are not merely technically proficient but also adaptable to our team and company dynamics. In my perspective, it is this amalgamation that genuinely characterizes a candidate's potential.

[@Broxerlol]

Eh, this is an L take in my opinion. From my perspective as a web dev, this is a waste of time. We use our tools. We don't make tools. I haven't been asked to do an algorithm interview yet and I don't believe any of devs I've worked with spend time practicing them. We're all successful and do our jobs well. If you're a low level systems developer then sure, they're important. But for most dev jobs they are just irrelevant and do not indicate a good dev. The time crunch presented with some of these algorithms makes them basically impossible if you haven't recently practiced the one you're presented. Especially for big tech. I helped a buddy study for interviews with Google, Amazon and Microsoft. He landed a job at Microsoft but got a curveball question from Google and they ended the interview early because it was obvious he wasn't familiar with the algorithm needed. He's a fantastic engineer but he didn't know what was going to be asked so he was instantly disregarded.

[@dealloc]

Is it good to know about them? Sure. Is it necessary to show if you know how to solve the travel salesman problem? No. It also depends on the context of the job you're applying to. Not every position require you to know how to implement a radix tree, just know when you need to use one at a certain point. Why not present a real world example of a problem you had to solve within the software you write already? It may involve some algorithm, but don't be strict about it. It makes it a better talking point, and more useful ideas are shared this way. Common algorithms are pretty much set in stone, so they are not useful during an interview, and doesn't really determine the experience of an engineer if they don't know when to apply it.

[@hunhhmm]

The problem with real world questions is that you'll be judged even more harshly as the interviewer will be more familiar with it. Part of the point of selecting neutral algorithm questions is the interviewer will be less biased.

[@dealloc]

@@hunhhmm Then you dodged a bullet. I have never had an issue interviewing with people who use their own internal implementations as the base of their interview questions and assignments. In fact, from one point it lets the interviewer know how quickly you can understand an unfamiliar system and how you would approach the unknown.And it lets you get an insight in how they are working. In the best interviews I've had, they'd even go through the assignment together as a code-pair session and use this as an opportunity to flesh out details. Note that these projects are based on _existing_ internal things that are already implemented and well-known within the company; it's a red flag if they haven't actually implemented it-especially if they don't let you know up front or compensate you for your work.

I'm a react developer and had a very abstract task with a lot of dependencies all over. Made a modified linked list and boom everything went great. So even in the GUI world, it can be good to know a thing or two about known algos.

Literally posts a bubble sort 'gotcha' and says he doesn't do them! When you've constrained the problem enough that there are obviously 'correct' and 'incorrect' solutions, that's a 'gotcha'. Real problems don't have ideal, provable solutions, just tradeoffs or judgment calls from experience. I'm far more interested in someone who can articulate the kind of tradeoffs they expect they'll have to make, which tradeoffs are 'bedrock' and can't be easily changed (async/blocking, event carried state, etc). I want to hear about cost, risks, likelihood of being wrong, implicit assumptions about the solution, etc. It should feel like 2 guys riffing on a solution and you choose the one that went the best, not just who scored the highest out of 100 possible points.

Currently a java developer, been a java developer for 8 years, just laid off once (and not because of performance) and that was 5 years ago, never knew about DS or algorithms in an interview, never touched a leetcode problem to get a job, I've been able to build a strong career just with my knowledge in the languaje and in the J2EE frameworks (spring, struts, jsf, etc) and in every interview i've been asked and tested about that. Nobody can tell that i'm not qualified to be a developer just not for answering algorithms or DS questions. It all depends of what the company needs.

Algo Interview Questions: Only if it applies to your Business Requirements There is no reason to test a potential employee on merge Sort and B-Trees if your current projects do not use those algorithms

[@orderandchaos_at_work]

imo interviewers should only quiz me on things I'm actually good at.
