I had three or four 30 minute one-on-one interviews with the different team leaders of IMO division. I then gave a 50 minute presentation on my doctoral work to the team leaders. I was taken to lunch by two employees who held positions similar to the one I was applying for. After lunch I had a few more one-on-one interviews and then I was done.

Process begins with a phone screen with recruiter, followed by hiring manager discussion, then onsite interviews consisting of several one-on-one sessions, where candidates are usually expected to deliver a presentation.
