I spoke to a representative at the Career Fair and they got back to me like a week afterward. The was a 30 min phone interview with three members and the questions were regarding team work, experience working in cleanroom, questions related to specific projects listed in my resume - the depend heavily on mechatronics and controls background.
After 2 days I got a message saying I got selected for On-site interview. Then the onsite from 8:15 - 2:30. I made a 45min presentation on a topic of my choice and then there were 4 one-one interview sessions with an additional lunch-with-Engineer session. The questions were a good mix of both behavioral and Technical. The technical questions were mostly related to the work/ experience as mentioned in Resume but also some general knowledge questions specific to the job. Awaiting a response!
