There is a ton of info out there about resumes, job interviews, companies, etc., etc. Here is one small piece of advice... up until the time they offer you the job (this means, during the interview), act like you definitely want the job. If you get to the interview and you already **think** it's not ideal for you, don't let it show. Keep a positive attitude until they call you back. Then make your decision, once the job has definitely been offerred.
I learned this from personal experience.
