My interview experience with TripAdvisor was hands down the worst interview experience I have ever had. I've spoken with others that have interviewed with them and I was probably an anomaly but for me the experience was very negative. I spoke with four different managers and all four interviews were technical in nature. There were no personality interviews asking what I have done or what I was looking for in the company. There was also no portion of the interview process that told me about the company or even gave me a tour around the office. It was basic "build a b-tree" type questions and that was it. I should have known that it was going to be a bad day when I showed up and my name was misspelled on the folder they gave me. I was escorted to a small office for the interviews. In between interviews I had to sit there for about 20-30 minutes while I waited for the next interviewer. This happened between all four interviews. The HR rep occasionally stopped in and told me "we haven't forgotten about you". One interviewer was very disrespectful because he was playing on his iPhone while I was doing my technical exercises on the whiteboard. I also waited after the fourth interviewer for another half hour while I waited for the last interviewer who never showed up and I was told by the HR person that "he was too busy to do this" and that was it. The interview process started at 9:30 and ended at 4:00 and there was no break for lunch. I know companies don't have to provide lunch but you would think that they would at least give you a half hour to go out and grab a bite. Overall, it was a very disorganized and slightly disrespectful process and had a conveyor belt feel to it. The technical interviews were very technical and in depth on par with Google or Microsoft. It was what you would expect from a tech start-up (i.e. not a reason for the negative review). Make sure you study up on trees and hash tables.
