I went through about 3 interviews via phone call. The questions they asked were pretty straight forward. They also would offer to re-word it differently if I was not fully understanding the question. Interview did not last more than 30 minutes.

Detailed without being intimidating. Instructive, very friendly, and ultimately quick. I had three interviews beginning with the Recruiter, then what I can only describe as a pre-screener who advised you about the process in better detail, and finally with the hiring team.
