Hi I worked at McDonald's for over a year.
Firstly, I was invited for an interview like you. This was a one to one with the store manager. They asked lots of questions and the ones I mainly remember are these:
* do you act well in a team? (Yes) can you give me an example when you have?
* have you ever been in a situation where somebody hasn't worked well in a team? How would you deal with this? The answer is motivate I think.
* what would you do if a customer was rude? Have you ever experience this before?
* if you had lots of things to do, what would you do? The answer is prioritise.
I heard back later in the evening via email and was called back to a group meeting where we all got the job.
That's all I can remember! Hope it's okay, good luck! X
