The interview process was long about 4 hours sitting down with several upscale engineers. The first three had very standard and questions. Mostly directed at current research and projects going on. The last interviewer was much more thorough and asked some basic derivation question on how to derive transfer functions from a physical system with a controller. Over all I would say that the interview was moderate to difficult. Only because 4 hours is a long time to talk about yourself. And if you haven't had a lot of experience you will run out of material.

Interview with HR rep and engineering panelists (2-4). Process can take quite a while before an offer is extended. Applied online and through career fairs. Overall fairly simple but it is a good idea to follow up with the recruiter to make sure they stay on top of the process.
