Four separate 1-on-1, hour long interviews. As an intern I applied for the Edison Program. In all honesty the interview felt like a formality. It was heavy on behavioral questions and very light on technical ones. It almost felt like a show and tell (without the show). After getting a feel for what I'd be like to work with, the interviewers wanted to know if I had any questions for them. I asked about what they did on a day to day basis and showed a genuine interest in their responses. It was very laid back.

Written that includes Tech and apti reasoning english. and in interview they are asking about design subjects..if your project will be in additive manufacturing then prepare well because they asked good questions.
