I applied online. The process took 2 months. I interviewed at ByteDance in Sept 2025
Interview
1 OA and 1 interview. The first part of the interview was resume screening, but the interviewer liked to ask techniques that you didn’t mention in the resume. The second part was two easy coding problems which can be solved within 10 mins.
