🚀 neetcode.io/ - I created a FREE site to make interview prep a lot easier, hope it helps! ❤ I didn't mention this but using Python helped me a lot because you can write MUCH less code. I know most schools teach Java/C++, mine did as well, but i would highly recommend a language like Python/Javascript. Here's a short video highlighting the benefits of Python: kzbin.info/www/bejne/m56xnH19rMioqbM

meanwhile im preparing to do my interview tomorrow in c 🥲

[@raiyan22]

still confused if solving these in python will be worth it or not, i am a noob btw and i loved this video of yours, earned a sub

[@naodderibe4148]

hello, I currently do my challenges in java because I am most comfortable, but I do know a little python. Would you think it would be easier to do these problems in python? and if so should i sharpen my python knowledge?

[@NeetCode]

@@naodderibe4148 I do think it's worth learning python, because it doesn't take too long and makes questions easier. In the past I used C++, but switched to Python and it's well worth it. I have never used Python at any job, only for coding interviews and it's the best decision I ever made.

[@XxM1G3xX]

I have failed 3 final round of interviews at this point, I got back to my interviewers to ask for feedback: I am lacking stronger/faster and more efficient coding skills. I won't give up and I will do these lists, because before I was doing random Leetcode questions and that way I couldn't find the patterns everyone was talking about.

@@jeremiahyoung4617 its a good list but honestly the top companies ask questions that are a bit harder, i did get lucky on a few rounds and got similar questions but for the most part these questions are just "part 1" and then the interviewers tackle on a bunch more constraints and make them harder and harder, which makes sense since they dont expect you to just memorize but its still VERY brutal.

Hands down the best channel for learning how to solve Leetcode problems! cheers

[@kylekeenan3485]

Just went through the interviewing process and none of the companies were interested in anything to do with algorithms but how I wrote and structured my code or how I approached a problem/code request. They are after people who know how to do the job not provide perfectly refined and optimal algorithms. This was a relief for me as KZbin would have you believe it's all about solving a random hard leet code example and completing it in 20 minutes and then optimising it on the spot.

[@sheturaj7437]

Nowadays seeing the question in the interview before is more important than directly cracking your head into the problem which you haven't seen before. Thats why people who got selected generally would have solved 300+ questions on leetcode.

[@tanoybhowmick8715]

This channel is blessing.

[@AdobadoFantastico]

This is a very useful approach.

[@kamertonaudiophileplayer847]

Yes, it is exactly what happens nowadays. People just learn how easy to break interview questions and get a job, but then we can observe tons of problems with software starting from a security and ending with understanding how software actually works. Hiring process should be seriously reconsidered.

[@DanielVazquez]

As much as I dislike LeetCode style questions, I find that they at least allow anyone to have a chance. Imagine a recent graduate with limited experience looking for a job. If every company would forget about algorithmic and data structure questions and instead they would ask about their own specific requirements and technologies it would be nearly impossible for them to prepare for every possible company.

[@thatoneguy978]

@@DanielVazquez someone recommended there should be a highly accredited cert you just show that you have

[@sdwone]

Yeap! I've been a professional coder for 10 years... Never used any algorithmic code EVER! It's niche exotic programming, for niche exotic coding jobs. Being able to write solid, well tested and easy to understand and maintain code, is vastly more important than being able to write fancy algorithms!!!

[@thatoneguy978]

@@sdwone but that doesn’t get you a job is the thing 💀 I’ve seen people who are grade A with explaining and handling code but get screwed over by algorithmic questions

[@SoyDelSouth]

@@sdwone there’s also a difference between software engineers and computer scientists. Engineers use software that is already made by computer scientists to develop their product. Computer scientists work with very low level, high math and very efficient code. You write Python? Computer scientists write the interpreter and other technologies that makes python accessible. While I do believe that the current interview system can be cheesed, by cheesing it you’re actually understanding very basic computer science concepts.

Still learning the basics of python and want to learn C# and Unity, so thank you for this video and spreadsheet resources! Hopefully by next year I'll be competent at coding and will be closer to becoming a programmer!

[@computer1889]

me right now is learning fundamentals of C# and then when i feel that the time is ready then i will ask them to buy me a new 2nd computer because I will transfer to my next goal which is to learn Unity and Blender... I am hoping on that time, coding is easy because at least I already learned some things of C# as wide as possible. *My first and only computer right now is a laptop that was bought in 2013, with intel celeron b830 1.8GHz 2 cores and it just costs 300 dollars which is very cheap = slow performance, so expect that it's really laggy/impossible if I use unity to practice. If this year later in 2022 I could have a computer it will be my 2nd computer in my whole existence(aside to smartphone)... but of course i will only ask them to buy me depends on my performance if I feel good and feel ready at programming then i will want to buy new computer so that i can continue to my next goal but in case i feel my knowledge is too weak, then i can assume my new computer would be in 2023 haha*

[@ambymbayi]

You are a genius!!!!!

[@scopeless22]

One thing you can also do is after completing a problem you can see code ranked by memory space and speed. Check out the high results for both, and don't just take the first one but look through them as there is usually a very streamlined approach that handles it while also being very readable. On several of those problems where I resorted to array lists or sets, simple array manipulation was used and was very well thought out.

Bro this is 🔥! I love the way you think

[@trrra]

I've been working as a backend and frontend engineer for the last 7 years of my life, but the majority of the tasks was so trivial and pure maintenance that I'm not able to solve, in a reasonable amount of time and with a decent optimised algorithm, even the "easy" problems. And this is really frustrating and tells a lot about choosing a company to work with and knowing when it's time to change

[@_yak]

I’ve been backend for 10 years and I don’t know anyone that solves these kinds of problems outside of interviews. Everyone needs to study for interviews because technical interviews are nothing like day to day work. In fact, in most contexts, if a dev is solving some tricky algorithm at work, they’re doing something wrong. There’s likely a well established library for it and hand rolling it will just make the code less maintainable and more error prone.

[@brittanyblassingill]

This is pretty normal and expected tbh.

[@RandomShowerThoughts]

@@_yakgreed, I never used anything remotely similar to these in my 3 years as a backend engineer

[@abz4852]

@yak to be fair majority of algorithms only show their use when companies need to handle enormous amounts of information which is really unnecessary at 99% of companies. Even large companies like FAANGS or large banks would be pretty optimised at this point. The only time this shines is in the rare case when a startup grows very fast into a massive company which is 0.01% of businesses
