TikTok Quality Analyst interview questions

Took 3 months to get an interview, with a colleague's help, who reminded HR about my pending CV. Finally the interview date was set. interviewer was late, 7 min interview lasted, took the whole month to get a rejection, only after the colleague who referred me in a first place wrote them email. Have a feeling they totally forgot about me because one of the recruiters told me I was pending for a second interview. So...

I applied for 3 positions and only got contacted after an employee referral. I did 3 interviews, 2 with the same recruiter and one with the manager. The manager asked questions very related to the position even though the HR was not able to explain the position in the previous interview. My last interview the recruiter told me about salary and benefits and asked if they were ok for me and I confirmed they were. I waited 6 days until I send and e-mail asking for a follow-up to receive after an e-mail saying that I did not get the position with a very general and automated feedback. I wen through all the interviews for the position and they were not even able to give me a proper feedback. Not to mention, the offer was the same as my current job, the only reason why I would accept was the opportunity to grow. In my experience they only contact referrals and the benefits are the same as every other average company.
