Ask questions of background. Get you on the phone in a real life situation, assess your ability to speak to people on the phone. Not expected to get meetings etc. Just enquiry calls. Given a list of names and numbers to call, and the directors listen in, to see your telephone manor. Great and active process. If only all companies gave you real life examples to work with!
Overall: They look for your character and personality, as well as your ability to use the phone.
