Do folks here solve all 400+ questions? Pick a random sample of easy/medium/hard questions? Or do you purchase the paid account and practice by target companies? Any tips from recent users will be helpful.

  • Nope. I solved around 90 problems. Among them, many are similar each other. I only used leetcode and got offers from fb goog uber and other start ups. It indeed works. But I am a senior engineer, so for me design questions were also important. I did not solve leet code questions that require eureka! or gotch! Ideas. Instead I concentrated solid fundamental questions like backtracking. Do not waste your time to cover all dynamic programming.

    • Interestingly both google and facebook questions required me to derive some mathematical formulas. It was hard.

    • Are you willing to share a sample of a design question that eventually need to derive a mathematical formula to resolve? Can't think of such things yet, may be I never experienced or didn't understand that they're looking for something like this!

    i'm on the other end of spectrum. did 160 problems in 2 months. got very comfortable with interviews.didn't get offer from goog. couldn't clear phone screen from fb. fb interviewer was very specific about the solution. i gave him an answer which had 2n comparisons . he wanted one with n comparisons, which i solved but not in an elegant way. he can go fuck himself with his solution. i'm going to try again next year

  • Purchased premium and sorted by most common. Worked exceptionally well. Many questions are duplicates or very similar and you'll get little value from completing all 400.

    Is this truly the secret to getting into our companies?? Whoever has the most will and time to study leetcode questions? Seems too easy...

    I don't think notepad helps. There are often times that u think ur solution is right until u execute with real test cases (on leetcode)

      Yes I personally thought that helped me catching all the corner scenarios and be a better interviewee. You can always say if 70% of test cases pass I am good and I will move along.

      yes, but it stops executing the remaining tests when it encounters the first failing test
