Customer service job interview - please help

[UsedToBeAPaxmanFan]

Hi, not sure if this is the right place to post but I hope someone can advise.

DS is looking for a customer service job and has got an interview for one with the local council. He's been told that he'll be given a "task based assessmemt" prior to the interview, and it will take 30 minutes. Has anyone got any ideas what sort of thing this might involve? I've done in tray/prioritisation tasks in interviews before, but that was many years ago and not sure what might be current now.

He's really interested in the job, and it sounds just up his street, so he wants to do as well as he can in the interview.

TIA

The assessment will depend on the area of the council in which he would be employed.

For eg. If he were working in the housing department which is very public facing, he might be tasked with answering the phone whilst checking housing application forms.

What area of the council is it?

Hi, thanks for answering. It's first point of contact, so not based in a department but presumably signposting/transferring callers to the department they need, or dealing with the straightforward queries. So he is not expected to have any specialist knowledge. Our council just has one number, all callers have to go through that. I just can't think what sort of exercise they could set for that.
