Horrible! I first applied in April 2020 and got contacted by someone in Bytedance HR (from China) a couple of weeks after. The person invited me for an zoom interview but I had no idea who I was going to meet and what the person's function was. As the job description I applied for was very generic I asked for a more details on the position but I was given just a copy-paste of the role I applied for (which looked like a google translate English from Mandarin). The person I interviewed for was actually very competent and helpful and explained me they were growing very fast and so the role I applied for was likely to evolve. She also mentioned I'd need to meet 3 other colleagues before the end of the process. After a MONTH I was notified by HR about a second interview with another colleague (again, they didn't share any job title) who seemed shocked by the lack of information I was provided by HR prior of my interview. He also confirmed I'd have to talk with a couple more people and HR will be in touch to schedule the upcoming interviews. Instead after an additional month I received an automated email saying that my application was unsuccessful. No feedback, no explanation even after I followed up. I know other people who are now in the company and had a good experience so I guess it depends on the department but if the Chinese team is managing the process just STAY AWAY

Interview process was relatively quick. I was approached by one of the internal recruiters on LinkedIn. Things moved pretty quickly. First stage was a video call with the recruiter, 2nd stage was with a manager. However I didn't get past this stage. I had to chase them for an answer as they didn't tell me that I wasn't successful.
