TikTok Software Development Engineer In Test SDET interview questions

I interviewed at TikTok online, after taking to recruiter, First interview was in Mandarin I can feel the interviewer was not very concentrate on the interview and no facial expression

The interview process was smooth. OA + technical screen + HM. OA is a bit different from general leetcode but focused on testing. Technical screen is LeetCode easy/medium. HM round is chill but somehow the headcount is full so didn't get the job.
