good. video question, test and waiting period for review. need to a bit of knowledge before going into these types of jobs. recommended brushing up on your technical skills. For me I was interviewing on my knowledge of programming and SQL.

First - Phone screen with a recruiter(after this, they gonna give you the study material and you need to study these materials really well so you can answer questions in the next round). Second - interview with the Senior Engineer(the interviewer gonna ask you some easy questions first and then harder-try to study on object-oriented topic!!!!)
