During a job interview, you only get about 15 to 20 minutes to sell yourself as the perfect person for the position. So, you don't want to blow it. You want the interviewer to get to know your attitude, skills and experience. Follow these tips on how to behave on a first job interview.

Show up for the job interview a little early. Being late is a bad first impression and can blow the job. Managers may think if you're late to the interview, you'll be an unreliable employee.

Use your body language to convey your confidence. Make eye contact and maintain good posture during the interview.

Relate your answers to the specific company or interviewer. This will show that you've done your research.

Speak professionally. Don't ramble or use slang in your answers.

Stay positive during the interview. Avoid complaining or bad mouthing previous employers or companies.

Ask the interviewer some questions about the position and the company. This is your chance to show off the fact that you've done some research.

Send a thank you note afterward. This will show the manager that you really want to make a good impression. Thank them for taking the time to meet with you.
