Same here, but I think the purpose of such a question is to see how comfortable you are with recursion, pointers, and abstract thinking.

[@Infinitely16]

If you get to onsites and they assume you can code by that point because of the previous leetcode interviews, and the onsites are about communication and collaboration, why are there more leetcode questions? Why not discussing past work, sharing a personal project and talking about it, walking through some code together with the interviewer and seeing how well the candidate can digest and explain what is going on, discussing open source development, etc. This is precisely a school test, the whole way through. Pretending that it isn't is unfair and just lying. I don't mean to attack you. But everybody, including these companies, know that these many leetcode interviews don't determine someone's competency and certainly aren't an indicator for if they will fit in at the company. It's just an easy shortcut. Communication is a weak point because in order to prepare *just* for the interviews, you have to go through 3-6+ months of studying leetcode. You can't communicate with the interviewer during the test, they aren't allowed to talk much other than vague hints here and there. It's weird to have to juggle thinking about solving the problem and trying to speak every 5 seconds because that's not how thinking works. It's just a weird industry practice and we all know it's a broken system. Everybody knows this, but as an industry we keep pretending. Sorry for the rant, I'm sure you and all of us can understand how insanely frustrating it is. Again, I am not attacking you specifically, just frustrated at the system in general. Needed to vent.

[@realalexnguyen]

Hey it's absolutely frustrating. I mean as long as someone can code that's all the should really matter. Here's some more thoughts just trying to help From the 5 onsite rounds, there's usually 3 that are coding, 1 behavioral, and 1 system design depending on the level. The behavioral is where people get to talk about past projects and how people handle work/people problems. This is where companies figure out what level someone should be at. (Did they lead a team or did they get led?) The onsite coding rounds do include tons of Leetcode. It's pretty unfair and I don't like it either but I have to admit that's just how it is. I wanted to make this video to mention that even when people solved the question it was just the communication holding them back. Something a friend of mine helped reframe Leetcode to be healthy for me was that once you feel comfortable doing most questions, it's a passport to any other tech company because the format is almost always the same. Wishing you best of luck it's been hard for everyone lately

Reminds me of the time I bombed out on an SDET interview, and the manager concluded did not have good coding nor good testing skills. Five years later, we crossed paths again. I was tasked with estimating the effort needed to snapshot a running Unreal game's log, a feature QA really, really wanted. This manager and his colleagues had deemed the log exclusively locked and unreadable. But, with a little interviewing, followed by some tinkering on a Friday afternoon, I quickly found out what they were doing wrong: they weren't opening the game log file with the correct flags. Open the file with the correct flags and it was instantly readable. Rather than an estimate, I delivered the feature itself, and saved the group the cost of hiring an Unreal engine developer.

Why would you ever want to reverse a linked list? That's a sign of bad software design. So I fail the interviewer and Google if they really design software like this! P.S : Interviewer Alex Nguyen goes to the captain of his ship and tells him : 75% of the new recruits don't know how to reverse the elements of the chain between the ship and the anchor! (although it is a bit more complicated with a real linked list) And the captain thinks "??!" and then tells Alex : "You are fired!" P.P.S, Now there is also this story why Cinderella can not go to the ball against the royal command because she has been given useless chores to do such as "reversing linked lists", kzbin.info/www/bejne/f5ypf3iLp7h3adk And so the moral of this story is that "useless chores" are invented by incompetent or not very talented people in order to sabotage the talented and brilliant ones that are threatening to their careers.... But in the end maybe the prince will still come and "marry" the talented and brilliant ones and leave the others to themselves!

[@sabriath]

uhhh......that's simple enough, starting at first, stored as "i" (our temp holding variable), swap prev/next values of 'i' object, then set 'i' to 'prev' (which was 'next' before you swapped it) and loop until 'i' is null and break out. then swap first/last variables, done. O(n) speed. failsafe questions for interview would be to ask if certain error checks are to be performed within the function base or if it will be done separately by a different process....error possibilities are bad pointers (simple 'try' capture with memory test on pointer, speed reduced per n unit by c1), circular listing (a 2-to-1 tracer would reduce speed further by an additional O(n) per direction), disconnected/broken/botched filing in the pointers (another speed reduction by O(n) per direction). Other possibilities are whether you have a begin/end train to flip rather than the entire list, which can be far more fun to play with. Yeah, problem is, as much as I could solve any problem extremely quickly, I don't usually work well with others or speak my problems aloud. I'll stick to indie game development for now, but it is still fun to do programming puzzles like these.

[@paulwilliams6438]

Source: lots of ppl I know got into faang, their skill is wide ranged, even ppl who only know code less than half a year (but with good degree or possibly STEM related experience). and the success rate has nothing to do with personal skill, it's all about leetcode + luck. During the hiring boom, even if you semi-fail the leetcode, you still got into the company by luck. Many also speak broken English, at least in US, it's a instant reject for small startups, startups can't afford those communication cost regardless personal skill due to budget limit. Big techs internally have a lot of strong systems that aren't open-sourced or shared. Built by many strong engineers in the past. Many new engineers even the veterans didn't have a complete picture what they are doing as a whole. Thing is so complex or due to company policy, they can't share or are incompetent to share. Many were just only 2 years in a big system and too early to know anything about the tech. Guess what they can share? leetcode that the resource is everywhere. As a result, you will see tons of ex-faang or current faang people only sell leetcode course + interview course. Are they better than you, it's unknown, they are just using their company brand to exploit you.

It's because too many people apply. At that point FAANG uses anything and everything to filter candidates out. At this rate, soon they'll add a new test of doing the maximum number of somersaults per minute, to qualify to the next round. A highly effective filtration strategy and there'll be websites and KZbin channels dedicated on teaching how to somersault and pass through the FAANG round.

Mostly agree. Especially the very firat issue. I was interviewing at Google for few years and rearly have seen even experienced engineer ask clarifying questions. Like dataset size, performance requirments, how often things need to be run (i.e. one of vs online repeatedly). We ask quesion without these details on purpose, so you ask for clarifications. If you don't ask, you are guaranteed to not solve the problem (no matter how smart you think you are). Also know actual numbers, memory, disk, network, cpu, etc. Not just your oh notation but constant factors. And dont go into all the details so you cannot answer first question of the interview on time. You are talking to somebody who is very experienced, and few well choosen words will suffice to deliver the message. Also don't trust everything textbooks says. There is a lot of ifs and buts, and assumptions , constant developments in basically every area of computer engineering. Even basica that most people think are "solved" decades ago. No they are not.

Interesting video! Within the past 2-3 years, my perspective on interviews changed. I don't go on many interviews and I DO NOT interview well AT ALL. Given those statements, I now view an interview like a "first date". On a first date, I'm presenting myself in my best light to make the best impression possible. I'm well groomed, I look and smell nice, and I engage in thoughtful and "clever" conversation, mostly to impress her. If we get together, I'll "relax" and show my "true colors". If we're not compatible, we split and I repeat the process and go on another date. lol I don't prepare for interviews anymore. The knowledge that I have is the knowledge that I have. If I'm confronted with something I don't know or can't remember how to do, immediately, I work through the problem or I do research to help identify a solution. I won't go to Stack Overflow and look for examples. I spend my time to understand the problem more so I can work through the solution. The point is, I won't have every algorithm in my head at any given time. The work I've done, throughout my career, has been interesting (to me at least) but hasn't involved much of the kind of knowledge I would need to "cram" for. If you asked me to reverse a linked-list on a blank whiteboard, it would probably take me some time. Why? I haven't touched linked-lists in DECADES. I'm more of a "hands on" kind of person. Give me a chance to actually do some work and I'll perform better than in an interview situation. So, I think a 3-month "trial" would be a better approach to vet a candidate. Pay them little (or nothing), put them on a "real" team and given them assignments. See how they actually perform. If they write garbage code, end the relationship and move on. If they don't work well with the team, end the relationship and move on. I used to "fantasize" about working at a company, like a Google, but I never really tried to do that kind of work. Sure, the money would be awesome but I'm not sure I would be a good fit for that kind of company/environment. I get contacted my recruiters on LinkedIn and sometimes I wonder why, because my work history doesn't match (at least not to me) what they are contacting me for, but I'm happy where I am now and I'm doing a-ok. :) Anyway, thanks for posting this video. I did enjoy watching it and listening to your tips and suggestions. Now, I'm off to see if I can reverse a linked list! lol

Honest question: if Ive been a developer with multiple years of experience and Im signing up for a normal software dev role, would you still ask me to solve silly leetcode problems? It just seems extremely weird when full-stack devs have literally single-handedly built and deployed dozens of apps for customers, only to not get to the next interview stage because they couldnt memorize a sorting algorithm.

There's a code question and it's largely up to the interviewer. The questions that I use tend to be simplified forms of something I've needed to do solving a real business problem.

Can you request mock interviews with Google if you are interviewing somewhere else? Also, I have been an SDET for 5 years. I’m edging more on the sr side. At this level, data structures and algorithms escape me. How important is knowing this in interviews?

[@89TStefan]

I can't get the idea of this leetcode obsession or mock questions. What does this even tell about actual programming skills? It just tells about how someone is able to remember standard answers. Let someone play half an hour in Shenzhen IO or Factorio and watch him. This tells you a lot more about his skills than any question in an interview! btw: Why would anybody work for a company like that?

[@bestopinion9257]

Geez! If you can't solve letcode you can't solve problems. You can't jump from your lazy routine when needed.

[@89TStefan]

@@bestopinion9257 Leetcode problems have nothing to do with reality. They are overall more like laboratory academic problems. In actual sw developer work, much of the code you handle is legacy.There are many, many side effects depending on architecture and infrastructure. The problems you have to handle there are a lot deeper and far more complex than any leetcode problem. Instead of using a general approach, you have to have a specific approach to the problem. And a general approach being taught in leetcode doesn't let you do shit on that but only own projects, strategy games, programming puzzles, no leetcode, no 100+ hours of udemy lessons, or worse, an university degree. I've had my own share of interviews with applicants. And it always boils down to the same very simple formula. Are you doing your own projects? Having fun at solving puzzles? Interested in gaming? Those are the people you actually look for because they show they are a) being able to work for a long time in front of a computer, b) actually have fun at that, and c) are, even when not asked, doing something to improve themselves. Meanwhile, someone being able to answer 100+ leetcode questions perfectly does not tell you anything other than that this person is able to remember algorithms (and is probably not being able to use it in a real-life situation).This is also very often true. Give someone a leetcode question. No problem. Tell him it is, for example, a problem which is being heavily modfiied from any leetcode question and 90% of people fail at that.

[@89TStefan]

​@@bestopinion9257 Well, the problem here is that leetcode problems are problems that can be googled. Your average everyday problem as a software developer just tends to be one where you might google a step or two, but the overall solving process has nothing to do with that or if you are able to solve it. And why even think about a problem, wasting time rather than understanding the problem, looking up a solution and then trying to fit it to your actual scenario, because that is what actual developers do every day. So someone being able to "solve" a leetcode problem or not is not telling you anything about his skills but a rather academic point of view which proofs nothing.

[@curiousintrovert1016]

Does what you said about run time, also apply to space complexity?

[@AlexJordan]

it's CRAZY to me that you can't run the code. stepping through line by line is an enormous waste of time and means that the person spends their time doing that instead of showing you their debugging skills when the code doesn't work. i work at a series A startup and this is table stakes for our interview process.

Yeah, Google literally cancelled their tests for us to even apply and get a chance and randomly picked students that got internship at google before or who had really high gpa. I have high gpa but it's not like 3.8 or something, and yeah they picked those only :) Talk about fair shortlisting.

Frankly, if you need to reverse a linked list then you have a bigger problem, since you shouldnt have used a linkedlist to start with if you need to reverse it. Probably should start to learn about data structures first.

Idk what candidates you are interviewing, I have never received any Interview call despite applying a dozen times. I have 2.5 yo experience out of college Still gets rejected 🤔

[@jasonfreeman8022]

I question the value of the process. First, most developers are introverts and this kind of “code on demand” filters out genuinely good devs who vapor lock. Second, the leet code approach is not even remotely real. Actual daily development tasks are far more mundane and only occasionally do you even get to the detail level required by high-pressure leet-code puzzles. The reality is the interview process is gate keeping elitism. I could easily construct interviews that FAANG devs couldn’t pass if wanted to be an ass. And when everyone wants to work for you, you can pretend that your process is great. When I interview candidates, I’m looking for technical understanding and “comfort”. An experienced dev won’t have difficulty conversing about architecture, data structures, language quirks, tools, libraries, etc. None of that requires writing code that you would only ever write once and you’d take an hour or two to compose.

[@notsojharedtroll23]

Yep. It is to become part of a club. Tbf, my "tech interview" was exactly knowledge questions about ML and got most of them right and tadá. Now that I'm part of the club, the mundayne shit is much more appealing that the dreaded code problems of such interviews.

[@zweibier42]

because, apparently, the work in Google involves mostly reversing linked lists or doing other stupid exercises which everybody forgets once they leave the college and which can be looked googled up in seconds

[@DavidConnerCodeaholic]

See my problem is that I need to get up to speed on a language or interview before I do it, since I use a lot of esoteric tools… so I know I’m going to fail. The interview timeline is too quick to get up to speed. Most companies (only in the past 5+ years) allow you to use any language… but it’s still better if you learn their language & framework. That’s too much work. I try anyways. It disrupts whatever fucking projects I’m working on and ultimately wastes my fucking time (sorry, it does and I fucking hate JavaScript) Even though I should have the skill for many companies, since I haven’t had a job recently, my only exposures to technologies are KZbin, source code (using Google’s Repo tool) and self-exploration. I’ve been looking for something non-Microsoft and non-Java script for like 10 years now. I would just rather program for fun since office politics basically gave me PTSD.
