Liberty Mutual Insurance Product Development Rotational Program interview questions

Went to a Q&A session on campus with a recruiter. Got invited to a 30-45 min. interview with a product manager on the team, and passed. Last round is at the offices, and is a full day event from 8am-2pm. Started with a breakfast and a Q&A session with current product analysts, then got split into groups. I had the case study interview first. Met with a product analyst manager and was given an oral/written case study. It was about what to do when trying to enter a new insurance market, and then was asked to perform basic calculations. Next was a behavioral interview, and then a job shadow. After the job shadow was my second behavioral interview. Then we went on to lunch. Got a call in 2 weeks saying that I would not receive an offer.
