Talked to engineer at university career fair. He was interested in the work I had done. Next day, I get a call from the recruiter during a lecture, so I could't take the call. I call back an hour later and left a voicemail. Didn't get a call back. Continued calling back and leaving vm's for a week but got no response. Apparently, TripAdvisor follows this approach when recruiting from career fairs - if you take the recruiter's call when they call, you get an interview, otherwise you don't. I got irritated at this irrational method and emailed the careers team email found on their website. Got an email from the recruiter(whose call I had missed) within the hour asking to schedule an interview. First phone interview - an hour of collaborative coding on a shared screen with a senior engineer. Engineer calls 45 mins late. Got through the interview and was scheduled for an onsite interview. Onsite interview - 4 interviews (1 coding, 2 algorithmic and 1 design) + lunch with hiring manager. Two interviewers were extremely friendly and nice. One guy(in the algo round) had quite a big chip on his shoulder. My solution missed one corner edge case - he pointed that out, walked out of the room (without saying goodbye) wearing an expression of 'how can you possibly miss that?'. Hiring manager was awkward and uncomfortable. Design round was really simple, but I'd no idea if my solution was what they were expecting as the manager kept saying 'ok' wearing a very confused expression all the while. Wouldn't have taken the offer if I had been offered one.
