Liberty Mutual Insurance Medical Services Representative interview questions

Applied online, received an email for an interview, or so I thought. I arrived at the "interview" to be put in a room with approximately 20 other applicants. We played a survival type game after we were put in 2 smaller groups. We were observed by managers. The "interview" ended with us being told some of us would be contacted for additional "interviews". I got a reject email a few days later. I'm not sure what this company is looking for. I have had countless interviews with them over the past few years...seriously, I have lost count. However, I will prevail! I refuse to let them NOT hire me. Good luck.
