It was pretty long a grueling. I had 6 back to back one on one interviews, each 30 mins. Then lunch with 4 of my interviewers which felt like another interview. Then had a case study where I was given basically a problem set and asked to solve/ explain answers on a white board. I had 2 hours to complete this, and I was left alone for this part. Then, finally, I presented/ explained my answers and thought process to a group of about 7 people who then asked my questions. In all it was about 7 hours
