Jonathan is a teen who got a job offer on the spot at his first interview. Why was it so easy? He dressed appropriately, answered questions in an informed manner, had questions to ask the interviewer and in general, made a very good impression on the interviewer.
In addition to good preparation before the interview, these guidelines will help you make just as good an impression as Jonathan did:
Be Polite: It's essential to have good manners when interviewing. Shake your interviewer's hand. Don't sit until you are invited to. Don't slouch in your chair. Don't use slang or swear. Be polite, positive, and professional throughout the interview.
Know Your Schedule: Know what days and hours you are available to work. The employer will ask. Flexibility is definitely an asset, because the more time you are available, the easier it is for the employer to set a work schedule. Also know how you are going to get to and from work, if you don't drive.
Be on Time: Arrive at the interview site a few minutes early. If you're not sure where to go, get directions ahead of time. If you don't have a driver's license, make sure you have a ride.
Go on Your Own: If your mom or dad brings for you an interview, don't bring them into the interview room with you. Go by yourself. It's important that you speak for yourself and connect with the interviewer, without someone else's assistance.
