Initial phone interview just asked about the basics of object oriented programming (linked lists vs arrays, etc). Second phone interview asked more about dynamic memory allocation and how to solve the problems that occur when dynamically allocating memory. Overall, all the interviewers were very polite and allowed time to answer questions even when stumbling. They didn't seem to know much about where I would be placed, so they just asked general questions about programming and computer science.

Very quick and easy. Was interviewed while attending one of their conferences for college students a few years back. Had one in-person interview solving a coding problem on whiteboard and another phone interview with a different engineer on background and generic conceptual questions.
