TikTok Operations interview questions

I was reached out to by a recruiter, I said I was interested, it took a while to connect to the recruiter. I spoke with the recruiter and the conversation was great. Then I spoke to a team member that had nothing to do with the role i was interviewing for and she wasn’t going to partner a lot with (odd). I candidly felt like I wasted my time, that they were fishing for ideas from me, and not interested at all in listening to my background or experience. Sure, if I wasn’t a fit for the role then, that’s okay, and I know I’m not going to get feedback. However, my last interview was about 3 weeks ago and I haven’t heard back from anyone nor gotten an automated system generated email rejection. With that said, I haven’t heard anything back and don’t intend to apply or consider Tik-Tok in the future. I understand the uncertainty of everything but a simple note would have been appreciated and interviewer beware.
