TikTok Senior Linux Kernel Engineer interview questions

The hiring process was three stages. All of them are 1-1 zoom call. The questions are solid and not difficult. The interview feedback process is negative. You need to chase them to get their feedback for each stage of interview. After the final video call, there were no communication and emails are not responded. After a month and escalated to global correspondence address, the HR reverted with the feedback as such they are moving with more suitable candidate. This should have been avoided and could have save time. And also, the job requirements and required skills are very vague and not related to the project they were describing. So, please be aware of it. The whole experience is not high standard.
