ByteDance Manager interview questions

Very unprofessional to begin with. I applied online and got a call from the company's China HQ for an interview with the team in Gurgaon. I wasn't briefed about the role and the product they're hiring for on the phone. Either ways, I decided to go forward with the interview. Reached there on time and after waiting for 10-15 minutes I met the interviewer. She explained a bit about the role and the product for which they are hiring. Asked me to share my experience with her. Didn't ask any challenging questions. It was all what I have done till now. I asked her more about the role, but didn't get a any satisfactory response. After discussing my experience and the product she asked me to wait for the second round. I kept on waiting for half an hour after which somebody else came and told me to leave as the person incharge of taking the second round wasn't available. I left and got a rejection email from their HR team in China a couple of days later.
