There was a technical phone interview at first. The questions asked included basic programming language concepts, algorithms, object oriented design, etc. Non of the questions were difficult, I think, but it's better to answer it completely as you can. The on-site interview started with an examination in paper , followed by a group interview with the team members, and finally an 1:1 interview with the manager. The exam is easier than my expectation. The difficulty is between Leetcode's easy and medium levels. During the interview phase, they asked a lot of behavioral questions, rather than technical questions, which impressed me. To sum up, I'm satisfied with the interview process and the salary they paid.
