Interview was for software engineer. I got the interview call through career fair at campus. It was a telephonic interview for 45 min. The interviewer was very polite and helpful. In the end I messed up things. It started off with the interviewer introducing himself, and asked to introduce my self. Then some behavioral questions, like why Facebook, which team, either Front-end or Back-end are you interested in, and a couple of questions on my projects and resume. The interviewed happened on a Thursday. At the end of the interview, the interviewer told "Sorry! Time's-up". Then itself I understood, I would not clear it. Next monday, I got a mail from the recruiter, that they can't move forward.
