Pocket Gems did a presentation at my school's job fair last year. I wanted to finish up a research project before starting interviews. I interviewed at Pocket Gems and four other technology companies. All of the questions were sort of similar. The first phase was a 90 minute phone screen with an programmer. Next was talking with a hiring manager about where a good fit would be, which we decided would probably be server programming (backend). Then I went to their office for a full day of interviews. The questions were all programming focused.
