Three rounds of interviews. One take-home task. Questions ranged from Java Collections, data structures, new Java features, Angular, JavaScript, multithreading, and databases. Tasks involved writing code, finding bugs in other code, and understanding Chinese, as the interviewer spoke Chinese while I was solving the problem. One of the worst interview experiences I've had in ages. The dumbest interviewer that I have seen in my life. He kept hopping on requirements and trying to be smart.
