Your first job interview can be rather scary! But I am sure you will be fine. You might want to do some preparation around the types of questions they might ask such as why you want the job, your stengths and weaknesses, experience you have and things like that. I would say you should dress smartly for it.. You could wear something like black trousers and a smart top would look good.
I wish you best of luck with the interview! Let me know how you get on
Since your job interview has already passed I'm going to go ahead and close this, if you want it reopened, feel free to pm me. I hope things went well, but I'm sure they did! So why not post a thread in the 'good days' if you did get it?
I think scars are like battle wounds - beautiful, in a way.
They show what you've been through and how strong you are for coming out of it.
