i honestly feel like they ask different questions depending on the manager?? i mean, my manager for my interview didn't follow a specific guideline for questions. it was just the regular stuff - why do you want a job here, what would make you good for the job, do you have any questions (try to think of one beforehand). i honestly just feel with my interview it was more how you gelled with the manager - in my case, we gelled quite well and still get along well now.
i don't think makeup should be an issue honestly unless you have an orange face, 2cm thick eyelashes, potato stamp blusher etc. and for my interview it said smart casual i recall?? and i just went in black jeans, a shirt and a blazer. i didn't get offered the job straight away but got called about an hour after.
