they usually do interviews in the staff room usually which is pretty bad really.
i was there 3 months i didnt even get a uniform, i kept getting warnings for not having one even though it wasn't my fault it was my managers. i also had holidays pre booked at the interview, it come round to the holidays they scheduled me in.
some weeks you won't have work cause its zero hour contract.
the job in its self is alright though.
the tips i give about the interview do your research i got asked do i know who owns the store? eg mike ashley, i got asked if a customer ****ged him off how would you handle the situation.
learn about general sales they have.
also you go to the main desk tell them you have an interview they will locate the correct manager. good luck
