The biggest problem with pen and paper or whiteboards is that I need to actually remember the legacy skill of handwriting.

One really nice thing about leetcode problems is that you can jump into one and finish it with very little warmup.

[@user-qn1np9gu5q]

@@and_I_am_Life_the_fixer_of_all it actually has a completely different purpose. People who invest themselves enough to get good enough at leetcode and then go through their extremely lengthy process to work for them are more likely to stick with them for longer, and happy about working for these companies. The entire situation where a lot of people look at these companies as their career goal is created and maintained by this ecosystem where there are learning platforms, contests, courses, youtube channels and whatnot. Another thing they really try hard is pushing for not needing college or masters education for roles. The more people they can add to an industry that has way more role gaps than engineers, the lower the salaries and benefits get...

[@matthiasramsauer349]

To be honest. I mostly experienced the opposite. In many cases the stack overflow solution isn't even a good direction to go in. Now I mostly look at source code because documentation is often outdated or incomplete and I test a bit around external functions to look if they actually work as expected or have some hidden bug. Especially apis are a bit crazy how many errors you can encounter that just aren't or false documented. Of course documentation is my first goto but if I can't figure it out with the documentation source code is the way to go. Edit: This might be a problem with the javascript ecosystem.

"Apply to companies you don't care about." may not always be a good approach because not all companies have the same interview process.

[@ehhhhhhhhhh]

I agree very much, but I have no clue how I'd find anyone who I'm confident can actually write maintainable, reliable, testable code. It makes sense to give several Easy LC problems to verify they aren't faking being a programmer, rather than giving LC Hard problems to try to find a "10X" super-genius-super-special impossible-to-work-with engineer.

[@jakejakeboom]

@@SolarShadoi work in embedded and honestly, there is very little usage of fancy algorithms, other than numerical domain-specific ones (FFT, signal processing algos, etc). I mainly write C in environments where dynamic memory allocation is prohibited, which makes 99% of cool data structures impossible or not worth it. I don’t think leetcode is very useful for embedded or systems programming, but maybe there are some good collections of problems for those domains im not aware of.

[@dealloc]

@@SolarShadoBut 99% don't and that's the point. The whole problem with leet code is that only pertains to people that already would know these things. Interviews that rely on leet code type of questions to determine a candidate's abilities are flawed from the get-go.

[@feitingschatten1]

I think I'm gonna start telling non-coders to tell me the hardest math they've ever done. Then I'm going to give them a time-limit and constantly pester them to tell me to explain their process. Then I'll judge them entirely on those 30 minutes, ignoring their work history and ability to explain their career beforehand. But first I'll make sure that my potential hires have autism to some degree, by ensuring it's a job with technical skills. Then instead of being sued for ADA violations, I'll become the standard, and force other companies to follow. Then I'll get youtubers like this guy to be so into it, he calls people who can't do it "dumb", regardless of how much code they've written and how clean it was. John Carmack's Quake code, for example, was OOP based, so clean a beginner could read it, and came out before leetcode... but that makes him dumb, obviously, because it didn't have this interview to prove himself, and likely would have failed. Q-bert was written by a 13 yr old. He too would've failed. Linux was written by some college kid.

[@hareepjoshi]

The irony is no one is stopping the unemployed programmer from creating the next Quake, the next Linux blah blah... also John Carmack, Linus and the kid would've crushed leetcode, if that was their thing.

So if you are not doing it on a regular basis, your mind will erase it. Unless you are gifted by the universe with a freaking good memory (not my case at all).

Solving leetcode or algoexpert problems is fun and challenging and will make you a better PROGRAMMER for sure, but does nothing for your DEVELOPER career imho.

[@SkyDread]

In our undergraduate studies in France, we have whiteboard sessions when a teacher asked us to solve stuff and roast us when we fail. Then grade us on the perf. You hear stuff like "why are you even here", "in one semester you are out for sure", "this is high school level math, and you still got it wrong". We were going in this hour of joy in group of 3 students and while you were solving your problem in one whiteboard in the corner of the room, you mate was being roosted by the professor. My favorite time was when my friend was done with the theory question and explain everything to the professor and the latter replied: "good, now you are going to demonstrate to me why what you just said is wrong". Don't miss it but if coding interviews are like that as well, the trick is to take it with a smile and don't pressure yourself too much, show confidence even if you are not sure how to solve and always try something

I had an interviewer paste a huge screenplay in the zoom chat of the happy number problem. I never have done LeetCode and have been a dev for 12 years. I have never got a LeetCode question in an interview until 2 months ago. I could not understand the problem at all. I said I dont understand the problem. With things like this I need time to myself to let the problem sink in. So he said ok lets do it as a take home and you finish it in your own time and email me back with the solution. So I did. I did some research and understood it and had a solution. He asked follow up questions and then I get rejected. I will from now on reject companies that do LeetCode questions OR if they do Codility/TestDome/HackerRank. Nope.

[@ErazerPT]

While i like stuff like leetcode and codinggame and etc, i feel like most times it ends up pushing people into "small domain" mindsets. Which is fine for "find the shortest path from x to y". But at some point I'll need you to "extend large domain x with new feature z. x is already a s**tshow of a system, how would you go about implementing z without making x even more of a s**show?". Now i might need an answer that totally runs counter to "best at the small domain" but is "best at the larger domain". Can the person do that shift if he has focused too tightly on the "small domain" issues? Can he understand that many times, there are tradeoffs? Has he become so familiar with the optimal solution that now he can't see he's trying to fit a square peg into a round hole?

i programmed on whiteboards - i think its much more common to code on programming apps where I care about variable names etc. On a whiteboard short names matter -- on a whiteboard often youll run out of space and have arrows going all over, it turns into a nightmare to follow really quick if you dont plan your writing space well.

Being good at leetcode tends to lead to shock and awe when the leetcode pro comes in on day one and is trying to work through legacy code with zero documentation. Best interview I ever had was a company that gave me a sample app where I had to 1: get 3 failing tests to pass 2: add a feature 3: suggest ways to make the app more efficient This is a much better approach that is more realistic for what you are going to do in your day to day. And the final suggestion piece can weed out those that cannot communicate well. Done.

this guy is hilarious lmao first funny programmer channel i've seen

[@coding_in_focus]

Where was this channel before it's literally a gold mine for programmers to find your channel ThePrimeTime.

you're good and crazy bruhh!

I’m not certain, but logically I see how leetcode can help point out gaps in your knowledge, but once you find those gaps i think it’s important to go out and make something that forces you to get better at whatever it was you were lacking in order to solve that problem. Leetcode can show you what you might need to learn, but in order to learn it you need to build stuff

where is the link to the free algorithms course??

[@SriSri-vm4nq]

Hey man where's the algo free course link?

[@MaxFung]

I blanked on a binary search on an array for a doordash interview last month it was so embarassing. best believe i remember it now

[@viis]

I love the seven different people who literally just copied Neetcode’s video and thumbnail, super cool

[@kanyesouth9397]

People should read introduction to algorithms, its a great book and gives you the mathematical foundation for how they work

[@thomasblaze]

Signed up for the Frontend Masters Bootcamp, but don't see any free algorithms course. Please share it, ya know - between diaper changes :P

Doesn't mean some else didn't have to

[@ibrahimhussain3248]

@@gandalfthegrey2777 Yes, true. That was not my point though. I do not think its a must to know in real life. You would know if you need it, I guess.

Yeah but data structure like binary tree are cool to learn but never implemented in my life

[@shu3684]

@@eunesshshahithakuri7047 never implemented but you use it all the time using a language api

I've implemented it once. I pulled in data from a crypto website and each coin/token started it's data on a different day. So I just picked the first day the company existed to check and then used binary search to find that first day where the data started flowing, for each token. So far the only time I've implemented it.

[@user-so9so7yi9g]

Where can I find the link to the free algorithm course mentioned in 6.32? Thank you in advance

[@mwwhited]

Algorithm questions for interviews are stupid. The correct answer for each one is do a search for the best algorithm then 1) use the version in your available standard libraries, 2) pull in a dependency that’s been tested and trusted by the community, or 3) implement it yourself but make sure to have proper test coverage to make sure you didn’t screw up. And typically if you have to get to number 3 the platform your are working on is not very mature so because for “there be dragons”.

[@romantruba8790]

I work in big tech and so often I face code that has 0 optimizations, n^2 and even n^3 solutions, or just ugly unmaintainable code. And often I question why do we even ask leetcode on interviews if no one uses it irl.

[@armax00]

I will need to share that first comment to all the people I know Your suggestion is sooo goooood, I will start using it when people ask me what to do for interviews :)

[@ignatrotenberg7676]

whenever i hear of leetcode, i instantly remember the "write your own atoi" challenge with 17% completion rate, where 99% of the comments are "who was the idiot who thought this is good challenge"

[@patrickaikonia853]

I have to agree with prime. Stack overflow and GPT3 doesn't have the solutions I need.

FYI: AVL Trees are balanced. Yes, AVL trees are balanced. An AVL (Adelson-Velsky and Landis) tree is a self-balancing binary search tree where the difference between heights of left and right subtrees cannot be more than one for all nodes. This property of AVL trees ensures that the tree remains balanced, leading to O(log n) search times, where n is the number of nodes in the tree. This makes AVL trees very efficient for lookup operations.. Source: Conversation with Bing, 18/11/2023 (1) en.wikipedia.org. en.wikipedia.org/wiki/AVL_tree. The example shown is unbalanced.

[@atijohn8135]

it is though: node 12's left subtree has height three, right has height two; node 18's left subtree has height one, right has height zero; node 8's left subtree has height two, the other has height one; and node 5 is the same as node 18 It doesn't have to be weight-balanced (i.e. roughly the same number of nodes in the left and right subtrees), only height-balanced

Where are all the interviews to practice on right now if you have less than 2 years experience? Crickets crickets. That is good advice for 3 years ago.

Good advice dude
