I had an interview with a small startup based in Michigan. The role was of C#/.NET Developer. The guy who interviewed me was the C.E.O. The first question he asked me was to implement an AVL tree from scratch. And I had no idea what to do at that time. I felt so bad that I was a computer science graduate from college and I couldn't solve the question. I just tried to explain to him that I studied AVL trees like 2-3 years ago and I didn't expect this question to be asked in the interview. The guy insulted me and told me that you need to practice a lot and be good at data structures and algorithms. And then he said that "Sorry, I cannot go further with the interview". I felt so miserable at that point and I was not able to sleep that night.
