There were four interviews. The first was an intensive behavioral phone interview. The questions drew heavily from project leadership and group management in my past. The second was a phone interview where I spoke with a member of the team. I was required to have my own questions prepared in order to have a better understanding of the position and display my interest in the position. The third was a phone interview with the head of the team where they asked me question pertaining to my past projects with a few behavioral questions repeated from my original interview. I was also asked where I saw technology in the next 10 years and then 20 years. The final interview was an in person interview. It was fairly informal and they pretty much seemed sold on me so I answered a few more questions, asked about some logistics, and was told they'd contact me soon.
