Three rounds of interviews: 1st: video interview. - the program asks 6 questions - record yourself answering each of the questions, you get one try 2nd: video-chat with recruiter - several behavioral questions - my interviewer was a PME 3rd: on-site interview - dinner with current program employees the night before - next morning you drive to the campus for two interviews, tour of the facility, lunch, and Q&A session with more current employees

It was pretty straightforward and easy, they really look for your behavior attributes rather than technical, but still the technical is important since the role is very versatile. I would focus on the basics and also understand customer interaction.
