Yes James, I'm well aware this isn't a major job. The truth is potential employers like to see you make an effort. If they see you can't even be bothered to dress smartly for an interview, it will give them the impression that you may well carry this on into the job and not bother there either.
.... and yeah, Peter, thats a load in a diaper right there. Sorry, but it's true.
They usually have a list of questions they're going to ask you to get an impression of you. Be honest and open, smile and carry
this attitude with you in the work place. How you look for a FAST FOOD JOB interview has absolutely nothing to do with anything.
How you carry yourself in simple one on one conversation makes a FAR... FAR greater impression on people than how you dress ever will. First impressions can be wrong, and if she gets turned away from the job before the interview even starts, then refer back to the last sentence of my previous post for my answer to that.
Tell me, how much money did you have for your first tie and nice dress up shirt at 15-16 years old for your first interview?
You're putting too much stock into "dress for success!" nonsense that usually only plagues big businesses and college graduates with degrees.
First job for a teenager in a fast food restaurant. Wear some jeans! I'd rather show up for an interview on time or early, in my school clothes, than be late because I had to run home, change, and then run off for it.
If they need the help they aren't going to give a flying fudge-sicle what you look like on the interview *to an extent*, AS LONG AS you show up for work in the proper work attire.
End of story.
