Google Software Engineer Internship interview questions

It was a phone call interview from Google. They asked me about my competitive programming profiles (my ratings, number of questions solved), past projects and GPA. The interviewer was friendly and calm. It was a good experience.

First, I was supposed to go through only 2 interviews. They both went very good and I was expecting an offer. Instead, I received an email asking to go through another interview. I accepted but the interviewer did not show up to the interview. They decided to schedule another interview of the same type as the first two. Again, I did very well, but I ended up being rejected. The whole process took 2 months, I think it is too much for an internship position.
