The interview is 50% personal questions about your resume, 50% behavior. After my initial contact with the company at the college career fair, and having completed the online application, a recruiter requested a 1:1 interview. However, I guess I didn't perform well enough on their competency screening (which is like puzzles) so I wasn't offered a further round. I would recommend you take your time on it.

After the skill assessment, started with a short HR phone screen, then a 1 hour interview, followed by an on site tour and final interview. All the questions were "tell me about a time when..." STAR questions.
