ByteDance Human Resources Business Partner interview questions

Phone based interview, I attended two interviews and was told I would be contacted for next stage but no one came back to me despite following up multiple times with them.

4 rounds. Not so clear. Some rounds are conducted in other languages. Recruiter is from overseas. Fast process moving averagey 1 rounds per week. More clarity will be better. Smart people as interviewers. They will make you feel at ease. Will be great if lesser rounds
