All day interview with different groups of people. Met with HR for 15 minutes followed by a 30 minute conversation with the Department head. Very relaxed setting with her. Then presented to a panel of about 10 people: 4 peers and 6 senior members. Everyone was very well educated and presented articulate arguments to my presentation. Then we broke for an hour lunch where I talked with the peers. They seemed to be determining my personality and culture fit. Last two hours were spent with the 10 people who viewed my presentation, split into two groups of five and lasting for one hour each. Again everyone was very intelligent and the panel was more of a conversation than an interview. At the end of the day, I felt like I did well but knew that they were interested in candidates who mightve been more qualified.
