People who interviewed me were so arrogant and clueless. They had no clue how to calculate time complexity. No clue why provided unit tests were not enough and etc. They were just looking at the solution and thinking they know everything.
If you displayed this type of disdain at the interview they might have caught on to it.
In the famous Joel quadrant of “smart and get things done”. You might have come across too much in the “smart” and not enough in the “get things done”.
I am venting here because I expected more from a company that is so proud of its interviewing process and I am disappointed.
