Tripadvisor Software Engineer interview questions

Applied through a recruiter in my school's tech career fair. Had an in-person interview the next day. An hour after my interview, I got an email saying I did well, and that they'd like to do a phone interview with me. My phone interview finally happened over 3 weeks after the original interview. They had me program on a shared document - so the engineer at the other end could see what I was writing as I was writing it. I didn't do too well, and a day later they sent me an email saying "thanks but no thanks".
