Pocket Gems interview questions

Started the interview process from Oct 2013. Asked LCA and some other similar coding questions. Got the offer in Jan 2014, but I was already pursing other interviews at that time.

I approached them at my school's career fair. They invited me to have dinner with them that night with a few other candidates. The next day they arranged interviews on campus, which where about 30-45 minutes and consisted of basic programming questions and writing some code on a white board. Following the on-campus interview they scheduled a phone interview. The phone interview included more basic programming questions and writing some code in a shared Google Doc. It was about 20-30 minutes. After passing the phone interview they flew me to their office in San Francisco. The interview lasted for seven hours, during which I sat in a conference room as various members of the development team came in and asked me questions. I was offered bathroom and water breaks but no food, nor was I told to bring anything to eat beforehand. Most of the questions asked me to describe or write code for an algorithm on a whiteboard. Many of the questions were the sort that if you'd happened to learn them in school or seen them somewhere online you'd be able to answer them right away, but if not you were screwed. Not the kind that you could reason through in a few minutes if you'd never seen them before. The last person to interview me was the lead programmer. I could tell from the minute he walked in that he didn't like me. While writing on the white board he would make comments about the syntax like "What language is that? C++? Because that's not C++." I knew at that point that this was definitely not the place for me (although the seven hours without food being bombarded with interview questions was another hint).
