How did it go?
If you are going to write a CV make it only one page - no more. Majority of employers will not be interested in reading past the first page as it's too time consuming and usually full of unimportant details. These days, your exam qualifications are not as important (in a lot of jobs but not all - depends on the position) as your personal experience so what you lack in formal qualifications you can more than make up for with relative experience. Do not make up qualifications and do not make up a job history - these things are easily checked and whilst the odd employer may find it amusing and think you've got balls for lying, many will see you as unfit to work in their establishment.
If you do not have references that you can think of right away, the words "references available on request" are invaluable! And don't forget, it is not allowed for a former employee to give you a bad reference so don't be afraid of putting down their name if you have to.
Above all, get a good night's sleep beforehand, check your appearance and ensure it is fitting with the position you are going for. Sometimes you can overdress which has the same negative effect as underdressing. Don't BS too much, if you have to at all, and be on time. Know a little of the company before you go too - helps to have an idea of the kind of thing you'll be facing should you get the job and shows initiative.
Then relax, make good eye contact, speak clearly and don't panic
