Eli Lilly and Company interview questions

I applied the beginning of Nov. for a full time employee and was contacted by one of the hiring team Advisors by email for a brief phone conversation the following day. I agreed and we spoke briefly about the position to see if I understood what the position was since it was a general description. About a week later the same advisor emailed me to ask for another brief phone call with a colleague to speak about the position the same day. I agreed and they called within 15 min. They asked a few behavioral questions which I was unprepared for and the call lasted about 15 min. I never spoke with a recruiter or HR before this. Two weeks later I get an email asking to come in for an in person interview with 4 people. I was asked all STAR behavioral questions and there was no questions about my experience or my resume. When I would answer the questions one of the interviewers would say that was the wrong answer. So confusing. HR finished the interview with telling me about the benefits. I left the interview feeling that I answered the questions very professionally and correctly and that I was confident that I had the position but the next day I was told I was not offered the position. I even had an employee referral and had worked there for 7 years as a contractor. I asked for feedback but denied.
