ByteDance interview questions

TL;DR: Huge waste of time. Very confusing with a lot of interviews that will take you nowhere. The interviews are scheduled one by one, so once I was approved in the previous round, a new one was scheduled. After 3 technical interviews and a "homework assessment" (which I had to work on over a weekend), I received a slightly confusing message saying that I could interview with another team for another position they had open. I agreed with the idea, and we started the process for the new position, after 2 other technical interviews (5 technical interviews in total by now) I was told I had been approved by the team, and I was going to be moved to their last step of the hiring process, a call with an HR representative to discuss a few other details before their offer. Several days after the last HR interview, I did not receive any feedback, so I decided to contact the recruiter, and to my surprise, I simply received the "standard rejection" (e.g the team decided to not proceed...) At this point I am very confused and disappointed (since I had been told I had been "approved" by their team previously), so I asked for further feedback, nothing concrete came on. I was once again offered to interview for another role, but I was told I would have to go through their interview process all over again, e.g Another 3 technical rounds. I decided to stop the hiring process at this point. I wish the company would've respected my time. Huge waste of time, 1 technical assessment and several technical interviews, many messages exchanged via email for nothing, e.g no offer made, no proper feedback shared.

Dress codes at ByteDance are casual, no need to carry a hard copy of the resume. The interview took on time without any delay. Everything was very systematic. First-round was the HR round The second round was Manager round
