I had 2 half-hour back to back interviews, one behavioural and one case. While the interviewers were very friendly, I did not feel like I connected with them. The names and positions of the interviewers remained a mystery until I actually met them, and even then one person remained without a last name or a position title. The other person introduced himself more thoroughly (he was a principal). I had 4 behavioural questions in total, 2 of which already exist on this site.
