I applied through university. The process took 1 day. I interviewed at Imerys (Lompoc, CA) in Jan 2011
Interview
Interview was fairly easy and consisted of technical and non-technical questions. Some of the non technical questions included "how do you manage projects", "describe a side project you have worked on by yourself", "how do you resolve a conflict in a group project?". And a few technical questions. The technical questions were very easy, some of them including "do you know what a PLC is?" and other simple questions about software and hardware.
