I respect you for that, but trust us on this one, a suit makes no difference. You will look and feel out of place on top of that. I can tell you are lucky enough not to have the misfortune of falling on hard times and have never signed on before.
They will spend five minutes on you - maximum. They want to process you and the fifteen guys behind you and they have no time for formalities. The suit just makes things awkward. They aren't there to help you find a job despite what the place may be called, that is your responsibility. They only act as the intermediate between you and the allowance you are given.
Fair point, I'm sure the process is as you describe and not something I am familiar with. I'd still wear suit for the initial meeting.
Rubbish. The Job centre couldn't give a hoot if you come in a suit or not.
If you read my posts perhaps you would understand that I consider it to be personal preference. I never said it was necessary but something that I'd personally do, whether people think it's strange or otherwise.
