At the interview, one person gave me basic information and asked me basic questions about my interests and experience. The main interviewer showed me their engineering room and hardware and asked me some conceptual questions relating to circuits and FPGAs. None of the questions are too difficult if you have a knowledge of things like voltage dividers, microcontrollers, FPGAs, soldering (surface mount). The questions asked are mainly to see how you answer, he wants you to "think out loud" so he can hear your thought process. The office itself (NYC) is pretty nice. It's very close to a PATH train station. I saw a lot of people working on computers and talking on phones, it seemed like a marketing team but i'm not too sure. The engineering room itself is fairly small because they don't have too many engineers, although I am not certain if they have other offices. Both people I interviewed with were extremely friendly and helpful.
