Reason

I interviewed for a position and the first two rounds were great conversations where we vibed really well together. I let them know I had another offer so they expedited the process and arranged for the third and final interview just two days later to meet my team. I felt like I killed it overall so I was so confused when I did not get an offer and was told to keep in touch in the future because the Team liked getting to know me. When I asked for feedback I was told that I didn't have enough experience. I have 7 years experience so it's hard to accept that as the reason. Give it to me straight, it was a personality and culture issue wasn't it?
