The 10 Biggest Interview Killers

When you're on a romantic dinner date, you try to avoid "mood killers" -- talking with a mouth full of food, cursing an ex-lover, or complaining about a foot ailment. During a job interview, you have to avoid similar spoilers if you want to make a good impression.

Here are 10 of the most common "advantage killers" and how you can steer clear of them during your next job interview.

1. Not knowing your aim. Too often candidates think their purpose in an interview is simply to ask for a job. Your goals are to demonstrate how you are a good fit for the organization, and to assess whether the job is really right for you.

2. Being too needy. Neediness is probably the No. 1 advantage-killer in an interview. Remind yourself before walking in the door: you do not need this job. You do need food, you do need air, and you do need water. Keep things in perspective.
