Phone screening interview, then all-day on-site interview. I had 9 back-to-back one-to-one interviews in the company cafeteria starting at 8 am, followed by hour-long presentation. Very exhausting so condition yourself beforehand. Some technical questions about my graduate work, and some behavioral questions ("example of problem solving..."), and lots of explanations of their own work. Tough interview overall, but it was a good practice, and I was treated well (financially).

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.
