Aliyah

This is my first job interview and although people say it's easy and stuff, I'm still really nervous, can anybody help me answer these questions?

1. What is your greatest achievement to date? (I've never had a job before and I'm not that involved in my school)

2. Name a time you did something wrong and what happened?

3. What do you know about McDonalds? (am I supposed to just talk about the history or?)

4. Where do you see yourself in 5 years? (I'm not sure if I still want to work at maccas, I'd hope I'd be in uni by then, what should i say?)

5. What are your strengths and weaknesses?

6. And what are potential questions I could ask at the end?

Would wearing just a normal plain black t-shirt (kind of v-neck but doesn't show that much of my chest area) and normal blue skinny jeans (not ripped) be bad to wear to a maccas interview?

I have a McDonalds Interview in a week and I need help as this is my first job interview (im still in high school):

-- How do I dress? I'm a girl and not sure what kind of top and was wondering if jeans was a bad idea (they're not ripped or anything just normal skinny)?

-- What does 'closed low-heeled, non-skid shoes' mean? I only own air maxes, could i get away with wearing them?

-- Where would I get interviewed? Like would I be in front of everyone or just by myself in the face-to-face part? (I live in Australia, VIC if that helps).

-- Just other general things I'd need to know, bc I'm so scared! (Questions I might be asked would help heaps and preferably sample answers to help me)
