What should one wear to an interview?

A suit and tie.

He should dress as if he were ready to go to work.

My husband has interviewed for the same position (and gotten the jobs) he usually wears dress pants (what do men call them, slacks?) a dress shirt, and tie. it’s damn sexy

For the interview, be honest. He should play up his qualifications, and if he knows a lot about running a restaurant, he should talk about that…like ask them about their numbers (like, the food cost is running, liquor cost, average guest check price per person what they do nightly in sales), the systems they run, there’s so much you need to convey to them that you know so they know you can handle it.

Suit and tie is de rigeur in a conservative colour, dress shirt, dark oxfords or the like for shoes.

@aprilsimnel I said it first, I just didn’t know it was the rigger.

Well, I’m just driving the point home. :) I wore a suit when I interviewed at a restaurant, too!

I agree, a suit and tie should give a good impression :)
Oh and I once heard that the first thing managers notice on ones interview is the “handshake”. They look for a strong and firm hand shake so make sure he gives it real strong! but not so strong to damage the other persons hand!

@mascaraaa, my dad wrote a poem he taught us when we were little:
There was a man
Who shook my hand
And gripped it like he meant it.

Another man
Shook the same one
And left a dishrag in it.

@Judi loves it!

Rule of Thumb: Always dress a little nicer for the interview than you would for the job.

@bonnalicious Welcome to fluther, dear.

I second that, and add: make sure your handshake is firm, eye contact, three second release and no sweaty palms.

Bon chance.
