I was contacted by the recruiter, had a 30 min phone conversation, and was set up for an all day interview on site. I ended up interviewing 5-7 people (can't remember exactly), all back to back with no break in between. I enjoyed speaking with everyone and people seemed to all have different questions for me, so it was not repetitive. Everyone also seemed to come from different places - some mores strategic, some more interpersonal, some more operational, some more tactical. It was a good series of conversations.
