Yelp's interview process was incredibly efficient compared with the other tech companies I have interviewed with. I gave my resume to one of Yelp's engineers at an on-campus career fair and was contacted later that evening to schedule an on-campus screen for a few days later. I struggled more than I should have with the question, but a week after the initial screen, they invited me out for an onsite interview at their office in SF. The onsite interviews started in the afternoon and began with a tour of their offices followed by a series of 4 technical interviews. Their engineers were very friendly and I thought I did well on the coding/algorithms questions. However, they also asked a fair number knowledge-based questions and seemed to be looking for specific answers--I definitely struggled with these due to my inexperience. I came out of the interview feeling pretty good but I received a rejection e-mail two days later telling me that I was not quite a right fit for the position. pros: fast process, interviewers were friendly, cool office in downtown SF cons: as one other review said, Yelp places more emphasis on knowledge-based questions than other tech companies
