They send you a HackerRank assessment to complete (LeetCode type coding test) as an initial step. You’ll need to get all of them completely correct as I highly doubt any of their engineers will actually look at your submission. Recruiter did not respond to my questions and sent an automated rejection, that if judged by the same standards as the coding assessment was, would be unacceptable.

The interview process was well prepared and the interviewees were really nice. There are 3 rounds: one HR round to test your English and expectation, one phone screen Technical round to test your working background, and some system design, one final round which also online with culture fit test, 3 technical with some of your future colleagues
