Pretty simple process. I had 2 rounds, one was a behavioral interview with around 5 questions. The second was a meeting with the hiring manager that was very relaxed. Overall, it was smooth and they got back to me pretty quickly.
The interviewers were very nice and casual, it seemed like they wanted to see your personality more than just your past experiences. They asked 5 behavioral questions after going over my resume.
There was a informational session before first interview, outlined the process. The interviewer only asked behavioral questions. There was only 1 interview for the entire process. Overall, it was super simple.
One interview that is a screening and is very quick and to the point. I would suggest going to all the events that happen before then to make sure you have the best shot though.
