> The interviewer can reject you because "They had a bad day" The only answer in your Quora link that has a lot of upvotes is by the author of CTCI and she is saying just the opposite, and instead of blaming the interviewer she is putting all of the blame on the person being interviewed. I find this quite disturbing, and you are right there isn't accountability on the interviewer, here are the things the author of CTCI is saying: > Maybe you came off as arrogant > A number of different things could happen. But when someone asks this question -- why did I get rejected even after doing well -- the problem is nearly always in the second part: You didn't do well > If you were interviewing with a big tech company, they have basically infinite programming spots. They don't reject someone because they found someone better; they just hire both. > So despite what you think about your performance, you probably didn't show good algorithmic problem-solving skills I'm all for self-introspection to assist in self-improvement but her persistence in ignoring the fact that interviewers are fallible is troubling, she is the go-to resource for probably most interviewees and interviewers and I don't like that she assumes that the thing that went wrong is "almost always" the fault of the interviewee. It's some grade-A BS.
