Its roughly 4 hours long. It was barely an interview process to say the least. The first hour is a presentation about epic, the second hour is a chat with a TS that introduces the role. The third part is a case study with another TS. I can't speak for everyone but my TS for the case study was super cold. He did not provide clear instructions as to how the case study would go. It was just weird interaction overall. That probably lasted 20 mins out of the 45 they give you. Last is a meeting with a hr recruiter, which was also a weird interaction. She was also super cold and asked a bunch of general questions to get a feel on your career. Overall I spent probably about 40 minutes actually talking to someone. Take this with a grain of salt this is just how my process went.
