After applying, and getting past the application process, it started with a codility assignment. So a coding challenge. If you do good at that (relative, I didn't ace it by any means, but I did solve all the challenges), then they move you on to a virtual interview. It seemed like the virtual interview was going to be one person but it was actually two, back to back in the interview. First was behavioral and the second was technical. During the technical they go over the problems that you answered in the codility assignment.
The interview process was fantastic overall. It felt very natural and the people were very nice.
