Four step interview process - Phone call, pre recorded interview, coding review and face to face (Via webcam) interview. There are usually a few days to a week between steps.
I applied through college or university. The process took 2 weeks. I interviewed at Optum (Boston, MA) in Apr 2017
Interview
Optum was hosting 1:1 interviews at my university, then an in-person interview with 2 alums of the program. The interview also included a tour of the building. All interview questions were behavioral based. I didn't have any technical questions.
