Words of wisdom from marketing Pro, Robbie Tarpley Raffish
2 Tips in one place!
An interview is not a conversation in a true sense - the only one who is really sharing is you. Be honest but stay on track; listen more than you speak and ask well prepared questions about the company.
Also: get a credit card only for work. Most companies do not provide "expense account" cards anymore especially to entry level people. You will do well to not commingle your personal charges with things for work for which you will be reimbursed.
