There were about 14 interviews, in batches of 3 or 4 each time. Interviews were a mix of video-conference and face to face, but always one-on-one.
Some interviewers were very technical, and wanted the details. Some of them were at a very high level. Once I joined, I realized that many tech-interviewers were very senior managers, while some of the fluffs were supposed to be hands-on folks.
