Tripadvisor Software Engineer interview questions

Went to the career fair, had a brief technical screening there and later that day got a call for an on-campus interview. The campus fair interview was basic with me going over my background and some basic caching techniques. The on-campus interview was 45 min long with a couple of questions. Some were database related and some were just writing the program for breadth first search.

Got an interview at my school's career fair, they did interviews near our campus, first interview was about 30 mins. I met one-on-one with one of the employees who interviewed me. After passing the first interview they send you "homework" to complete within 48 hours - I didn't get a warning about when to expect the homework, just got it sent to me and told to complete it within 2 days. The homework didn't take too long, maybe 3 hours in total. Still going through the interview process so I am unsure about whether or not I have the job yet.
