Pocket Gems came to my school as part of a job career fair, and I liked their presentation enough that I came to San Francisco to do a series of on site interviews. Some of the interviewers were really hard, but others asked a lot easier questions. It was a nice trip to SF. Their office is pretty cool. I especially enjoyed playing pool with some of the other developers there.

I initially contacted Pocket Gems through the career fair at my university; I gave them my resume at that time. Shortly after that, they contacted me to schedule an initial technical interview with a software development manager. The first interview was difficult, but I apparently answered the questions well enough to be invited back for three more technical interviews with Pocket Gems software engineers. I went through a total of four in-person 1-on-1 technical interviews, each lasting approximately 45 minutes. After I completed those interviews, a recruiter notified me within a few days to notify me that Pocket Gems would be offering me a job, and a different recruiter contacted me a couple of days after that to give me the specifics of the offer. My advice: the interview questions will be difficult, but be confident, explain your thought process well, and retain your composure even if you think the interview is going badly. You might be doing better than the interviewer is letting on.
