ByteDance Developer interview questions

Applied online. No phone screen, the recruiter just told me to show up at a given day without telling me what the interview was about. Turns out this was the onsite round. Asked for a gcal invite to add to my calendar, the recruiter just sends me the date and time stamp again. LOL. Afterwards they didn't even have a whiteboard, just a piece of paper. One interviewer round insisted on doing everything in mandarin, even though I barely spoke it. Afterwards I waited for an hour for the last interviewer to show up, turns out they were stuck in a meeting and told me to come back the next day. Afterwards they never replied about whether I got the job. Overall I wish the recruiters and employees
