Let them take their time. I have an idea that we should share our interview experience so people may get some help out of it in future. When I returned from interview the CSS Forums' servers were down and I was unable to do so.
Here are my interview (AD airport services) questions:

Introduction
Tell us about your family.
Tell us about the history of your district (followed by some detailed questions).
How (much) good son are you to your parents?
What do you think of the phrase "customer orientation"?
Aap ko koi shere aata hy? Shere suna!
If an annoying customer comes to you and starts a rude conversation what would you do? (I said I won't take it personal, rather I'll find a way to help him/her). Then they asked does it mean that you don't have ego?
