It was bad timing on my part, and while I knew most of the concepts involved, I was hazy on a few of them, which I could have easily resolved in another situation.

I want to mention that the last interviewer was extremely rude, interrupting and cutting me off mid-way through my response, indicative of an intense, almost personal dislike, which is very perplexing since I never knew the guy.

Towards the end of the interview, during a conversation gap, he quite obviously but very delicately called me a profanity. I was shocked and wanted to end the interview, which fortunately was going to end anyway.

Mostly technical questions. They never provided a keyboard and display so I could type out my answers, which is very strange. I felt like I was being judged on my handwriting.
