Process was detailed, long, but not overwhelming. Began with typical HR opening interview to ease you into the process, then was followed by 2 hour long technical interviews. I didn't do great, but it was my first interview of such type.
First technical interview was relatively vague how would you implement this broad process. The general nature of it made it a bit hard to dive into the problem as someone who had not had much technical interviewing experience. However, I believe this kind of question is pretty standard to assess your understanding of broad topics.
Second section was standard questions about object oriented approach. Questions consisted of designing objected oriented approach to a problem with code and then explaining how you might test it.
A great learning experience.
