phone screening first, and then onsite. Met 4 groups of people when onsite, the questions from management are mostly behavior questions, and the rest of them were technical, but not very hard. Asked some Java/C++ related questions. That's it. After on-site interview, waited for a couple of weeks and got the offer. The salary in the offer was disappointing but they insist that's their best offer. I took it in the end.

Take-home assignment, and they asked me a hard problem on Leetcode to solve. I solved that question, pushed it into the GitHub repo and submitted it to the interviewer. They rejected me with an invalid reason, stating that my approach was wrong and ghosted me later on.
