Applied through their webpage and heard from them one month later to do a code sample. After two weeks, received an email asking for possible times to schedule two interviews back to back.

First, an online assessment, then the HR call, then several rounds of technical interview (you need to solve data structure/algorithm problems), and finally a manager interview (mostly behavioral questions).

I had two online interviews with their software engineer. They first asked me about my research at school, and then we started the coding question part. The difficulty of the problems is around medium to hard on LeetCode.
