ByteDance interview questions

Recruiter scheduled my interview in EST hours instead of PST (even though I’d specified I was on the west coast), then they called me an hour early. Despite scheduling issues, the screening was fine and recruiter was pleasant. Follow up interview was with the hiring manager, who was very cagey and defensive and gave curt responses/couldn’t answer some of my questions. I asked what changes they’d implemented based on employee feedback, and she couldn’t think of any. Big red flags. She also said I wouldn’t be working on things specified in the JD. I spotted several typos in their app and suggested I could help QA app copy, but she didn’t seem to care and said that wasn’t what I’d be working on (even though product copy was specifically mentioned in the JD).
