TikTok Machine Learning Engineer interview questions

Make a appointment, and the people in China, it is late night. Dfs to solve island problem, not sure lc number, then go through my cv and ask quite details about my project. It is not a casual question, they ask by combining the application scenario.

The process was smooth overall. But extremely bad respect for interviewees. I got through all 3 rounds but they cancelled my call with the HR for discussing compensation just 1 hour before the call. Got no feedback as well got ghosted. All three rounds were similar 2 technical with devs and 1 with hiring manager consisting of resume dive, regular ml questions and a leetcode question.
