TikTok Software Development In Test interview questions

They have total 3 rounds. Interviewer in the first round was sensible and asked questions related to the position. But the interviewer in the second round hardly could speak anything in English, he kept asking technical questions(completely unrelated to the position I applied for) for 1hr and 20mins and later gave leetcode hard question. He didn't even give 5mins to solve the problem and said it was beyond the 1hr interview time and ended the interview. Their interviewer's knowledge & communication shows how the employees would be.
