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.

First presenting my research slides and Q & A for about 1 hour; Then solving 2 high school level math problems; Then presenting an exploration scenario to let you compute how many CDPs in this survey.

Interview was easy. They asked basic maths physics questions and introduced their own tech work and ideas. Lasted about 2 hrs. I talked to both the recruiter and a member of the image analyst team.
