Had an initial call with the recruiter and he was very quick in setting up a phone interview. The phone interview went on for an hour. The question given to me was totally new and I had to think very quickly to solve it efficiently within an hour. Before applying I did some good work practicing data structures, that came really handy. I was able to solve the solution very efficiently (constant time). I was sure I would be called for the next round but unfortunately I was not. The recruiter was prompt in getting back to me. They were not able to provide a feedback on why I was not selected for the next round. Would have been nice if I had got the feedback!
