Pre-interview, the HR were spookily friendly bordering on the intimidating (phrase that stuck: "they will go deep!" meaning that the interviewers will get to your deepest thoughts - they didn't). I gave two presentations about my work. Senior employees asked typical HR questions and others pertaining to my background. They gave me a crisis scenario to respond to as a CEO. The HR person sat there throughout, banging the keyboard. Had friendly lunch with a potential colleague, to see if I matched I suppose. Spoke with all team members. I was there at HQ all day.
