The interview lasted 24 minutes and ended very badly. I was not expecting a technical interview; I was expecting a more general and recruiter kind of talk. The interviewer asked me about SQL syntax, which I felt was not a good estimate of my programming skills. The second part, OOP design, was very difficult: implement a version control system. I totally blew this problem because I was overwhelmed by the complexity of a VCS (I use Git, so I was thinking about Git the entire time), and was not able to focus on the bare minimum components that made a VCS work. There were few hints. The questions were harder than my Google interview questions. I consider them very difficult for the entry level job I intend to interview for. Maybe there are people fresh out of college capable of answering those questions, but they certainly will not end up being at TripAdviser.
