45 minute one on ones with 5-6 people, mix of behavioral and technical questions. 1 hour presentation with Q/A on my research experience. 1.5 hour lunch fairly informal. We spoke mostly about the job culture. The managers I met with were all from different areas so the questions varied wildly from things like sorting techniques (CS) to semiconductor physics. Not sure why some basic concepts which are quick to learn and covered in every undergraduate curriculum are asked. I can't imagine most people will remember everything they've learned when put on the spot. Team seemed friendly and the atmosphere seemed very good.
