TikTok Machine Learning Engineer interview questions

HR screening + 3 rounds of technical interviews. Each round include resume deep dive, focusing on past research experience and innovations in transformer-based models. Then a medium to hard level coding.

Questions cover implementing Breadth-First Search (BFS), and a coding question using the priority queue (didn't exactly remember the question). The technical question includes understanding BERT in machine learning, including how it is trained and the model architecture.
