I had an one-on-one interview with a current employee and then 3 weeks later, I was scheduled for a panel interview onsite. The panel interviewers just wanted to know how I dealt with people and whether I can deal with ambiguous assignments. Overall, the job doesn't seem very difficult - it's just whether you are a people person or not. Otherwise, there is no negotiation on start date and the offer process is outsourced so it was impersonal.
