TikTok Client Solution Manager interview questions

I applied the position and within 5 days the TA reached out. The 1st interview is peer interview, second one is hiring manager, third one is director. In the first interview the peer was late for 15 mins and started asking questions, I answered and could feel she didn’t have anough experience as I did, finally she said it’s a great call and she has learned a lot from me. Later next day TA came back with the rejection without any reasons and they refused to provide feedbacks.
