The initial phone screen took about 20 minutes. It was more of an informative call, tell candidates what the position entails, what they are looking for, and the interview process if you make it to the second round. The questions were the usual generic types: what are your goals, why do you think you are qualified for the position, what are your future plans (it seems like there is no real career growth opportunities with this role, although their website shows a flowchart showing your potential career path starting as a research associate).
The 1:1 interview took about an hour. The interviewer (manager) had a form which had questions and she basically just asked each one in order. "Give me 3 examples of XXX, 3 examples of XXX, 3 examples of XXX." She did not seem too enthused for the interview. I don't blame her, she seemed pretty busy that day. However, I am not from D.C. and had to travel for the interview. She seemed nice but I never got a call back or reply back from her.
About a month and a half later (I had given up on them by now) I got an email (from the person I conducted the phone interview with) that I did not get the position.
