Turn around was very quick. The technical presentation Q/A session was the most intimidating part of the interview. The on site interview started with a short company presentation, the technical interview, two rounds of interviews, group problem, lunch, and the fab lab tour. You come into the on site interview with a presentation ready about a previous project you have done. The stages of interviews were a mix of behavioral questions and questions on your resume experiences. Most of the technical questions came from the presentation you present.
