ByteDance interview questions

Introduced experience from resume. Asked a few questions about open questions. Passed the technical interview, but don't know why I was rejected after HR interview. The HR may your background during the HR interview.

I had a 2 week long interview process. I first spoke with the recruiter who passed me on to the hiring manager for the role. The hiring manager asked me to complete a project and then to speak to 2 other Partnership teams where my experience may better align. I was not given any guidelines or timeline for the project. After getting through a total of four phone interviews, the recruiting coordinator followed up about the project. Ten minutes later I received an automated message saying the role was no longer open. When I asked the recruiter to confirm if it was still available, she simply copied and pasted the same automated message in her response. I never received any feedback. There seems to be some hierarchy and structural issues within the company, as well as communication issues between recruiters and hiring managers.
