I just took the OA test, there were only two questions, the elevator and the SQL. The SQL one was pretty hard. The next day i was rejected because of lack of experience.

Online test first, then a technical phone interview but without coding, then assign you a small project to finish, then on-site interview based on your project. recruiter and people who interviewed me on-site were very nice. However, they promised me the result will be given in one week after the on-site interview and they delayed another week.
