Centene Internship interview questions

(A 5-month process) Connected with a recruiter through a student organisation event, did an interview, then got rejected. The recruiter then referred me to another team, did an interview, and then I got rejected again. Then the recruiter referred me to another position, did the interview, and I got rejected again. Then the recruiter referred me to another position, but I rejected it. Never mentioned the reason for rejection, I appreciate the recommendations though, but wouldn't do it again.
