Leetcode unseen problems

Jun 1 61 Comments

Even after solving 150+ Leetcode problems (roughly 20% easy, 70% medium & 10% hard), I am having issues solving unseen problems in interviews. If that wasn't enough, in one of my onsite interviews at a FAANG I wasn't able to solve a seen problem that I had solved 3-4 months back. In another I wasn't able to recognize a previously solved problem that was (cleverly) worded differently.

I feel like I can never get in to a FAANG this way.

Am I alone? Any suggestions?

    Just solving the problems isn't enough. I recommend applying the "deliberate practice" methodology to your preparation (see books by Newport and Duckworth). By the end I had hundreds of flashcards I reviewed daily and made sure to come back to problems I had trouble solving the first time. In the end I got 12 offers and made it into my top choice (Google).

      I'll sell them for $10K. Making them is part of the process

      Lol working at Google and trying to get $10 haha. Although making them will be helpful too I think. The brain retains things as your write.

      You never learn anything from receiving a pack of flash cards.
      You learn more from figuring out the solution, writing them, and reviewing them.

      Are you talking about the books "Deep Work" by Newport and "Grit" by Duckworth?

      Yep. And for those of you who are lacking motivation I highly recommend reading Newport's "So Good They Can't Ignore you" first. For me personally this was the most important book I read.

    It's just random and broken, keep trying, you will eventually have a better interviews. It seems more of a game of persistence nowadays.

      So natural born intelligence has nothing to do with getting into Google?

      IQ does help for interviews, people with higher IQ will definitely have an easier time solving these puzzles on the fly and recalling the correct patterns to use.
      That does not make them better as a software engineer, but I do agree they can get the job easier.

    I can’t answer your question, but if this truly is the way tech companies interview these days we are doomed. We should be assessing potential and experience. Why should it matter how much leetcode someone has memorized?

      Welcome to the tech interview, where everyone knows its dirty and wrong but ultimately doesnt care enough to change it industry wide.

      Is “memorizing” leetcode even possible?

  • Amazon / Eng ewjX55
    Dont just keep leetcoding. Its clearly not helping u anymore. Ur problem is recognizing the problem for what it is. Ima guess that u also struggled with the word problems in Algebra or Physics

    Basically u need to understand the core comcepts, not just memorize. Why dont u refresh yourself on data structures and time complexity. Probably are good youtube or online courses on that

      Some people need to study leetcode really hard to internalize it. They are making up for their low intelligence by practicing extra hard and that's fine. I never understood why some bloggers would write about quitting their jobs and studying out of textbooks for months to interview at a big 4. Like, you're essentially announcing to the world you're an idiot but whatever.

  • I think it is normal to struggle a little bit with new types of questions and it happens to everyone. I do also struggle with new problems after solving 400+ Leecode problems. I have a PhD in Algorithms and I have been teaching it for a while. It is totally normal to bomb the interview and the interviewers know that, but it is not their concern. By this procedure, they are trying to minimize the false positives and it is kind of working. So in order to succeed you need two things: a lot of practice to minimize the struggle, a lot of luck to get easier, more familiar types of problems in the interviews. So, basically, you need to keep practicing and keep applying. Don't forget, you need to pass this barrier once.

    You can keep leetcoding but focus on being able to categorize them better. This way you can at least have an acceptable answer and optimize it with hint from the interviewer.

    I think your leetcode strategy needs little change. Try as this brother suggesting - https://medium.com/@alimirio/how-to-solve-problems-on-leetcode-to-prepare-for-technical-interviews-e74781b865d2 . He also created a video, you can look in YouTube.

    The goal isn’t to memorize problems, but to get good at problem solving. Having your tried mock interviews with Gianlo or PracticeCodingInterview.com?

    why u do leetcode is to recognize patterns jn problems. Once u recognize enough patterns u can solve majority of problems
