Met TripAdvisor at the campus job fair at UW Madison and after a couple of questions on complexity analysis of basic data structures, was asked to meet for an on-campus interview the next day. For the interview, I was asked questions based on divide-conquer recurrences and some more complexity analysis- nothing unexpected. I think my solution worked and even the interviewer thought so, but I got a message from the HR saying they had decided to move forward with other candidates.
