I just had one of these! Too late for the OP but this might be useful if others have interviews to come...
Basically there were 12 of us there (roughly half guys, half girls). All guys but one wore shirt and trousers, the other was smart casual (shirt with jeans). Some wore ties. None wore suit jackets but most had a vaguely smart looking coat. Girls tended to wear "smart casual" I think - fairly businesslike but no suits!
Overall lasted an hour and a half. Consisted of:
- Watching a half hour video on customer service - featured employees telling stories about how they have gone out of their way to make customer happy, secretly filmed mystery shop videos of good service etc.
- Talking to the person sitting next to us for 10 minutes then introducing them to the group.
- A slightly insulting test where we were given 10 pairs of catalogue numbers and had to put a tick or cross next to each pair to say if they were the same, and then had to put 10 catalogue numbers in numeric order. (To make sure you are able to go into the stock room and pull out the thing the customer actually asked for, obviously...)
- Working in groups of 4 to design a "customer service superhero". To see how we work in a group, and possibly also to see how much of the customer service stuff in the video at the start actually sank in!
- They also took photos of us at the end "to help put names to faces afterwards". Maybe if they have trouble deciding they will just pick the good looking people (that's me out...)
No individual interview, they will just let us know by the end of the week. Pay is minimum wage, contracts are for either 10hrs/week split across 5 days, or 7 hours at the weekend. Contracts begin next Monday (18th Oct) and end on Christmas eve for some, or the end of January for the rest. Obviously this all varies by store - mine was a small-ish one on a suburban high street a few miles out of Birmingham centre.
