First 1.5 hours with staff currently holding the position.

About 30 minutes with the direct supervisor. They will ask you situational questions and how you would deal with them, in my case with respect to dealing with customers. They also asked my views on certain challenges encountered with other team members and how to overcome them to work together effectively.
