Tips and Suggestions:

  1. Kindly explain your thought process when you are trying to solve a problem or designing a system. This will help the interviewer know if you are heading in the right direction and might help you in case you are stuck.
  2. Please don’t try to solve problem with the most optimal solution in the first go. If you know the naive approach start with that first, this will give interviewer an impression that you have capability to solve the problem. Once you have the naive approach then try to optimise it by discussing various approaches.
  3. Please don’t give up after 2 – 3 attempts keep trying different data-structures and algorithms to solve the problem. This will show the interviewer that you have never-give-up attitude and you have knowledge on other topics as well. If you follow this approach you will ultimately end up in solving the problem with at-least a naive approach.
  4. For System Design you can go through website (Paid course but worth it) and videos from Gaurav Sen System Design Videos:
  5. Please don’t get disappointed if the interview results were not positive. Remember that company could have various other reasons to reject the candidate irrespective of interview going well. Learn from your mistakes if you had done during the course of the interview and take that experience for future interviews.
