Received a phone interview after submitting a resume. The whole process is asking math questions. Spent around an hour in total. After that, get emails indicating that whether you are accepted or rejected.

First part of the interview is via on-line video conference and it is recorded for not only your response but your answer preparing process. This caused lot of confusion because it was not clear how they will conduct it. There is no person involved in during the interview process, but I guess humans review it after the video interview is complete.
