Phone HR interview. No programming test based on experience. They did call and talk to my references.

Called onsite. It is a weird experience since so little of it focuses on the interview.

There's a tour of the campus with a demo of the software and then a math test, followed by a case study, lunch, and finally 'the' interview.

I liked the case study because it was more of a brainstorming sort of problem. The actual interview was both painful and silly. All about a game with Xs and Os.

The math test is pretty challenging towards the end. Do not dawdle rechecking, etc.

HR can get a bit creepy about wanting to know about every single time period on your resume.
