At 15, it is probably not necessary to get dressed up like you are going to church. It depends on where you are interviewing of course, and if it is at a private club or some other higher end establishment, you might do better if you do look very respectable.

For most teen jobs though, the managers who are hiring 15 year olds and other ages probably only expect you to look clean and presentable. In other words, don’t go to an interview with ripped jeans and a tee shirt. Find the best pair of jeans you have and one of your better shirts to wear and you will probably be fine. Again though, this would depend somewhat on the job you are interviewing.

If you are in doubt about what to wear, use your common sense and also ask your parents for their advice. The one thing you don’t want to do is lose the job because of the way you are dressed. If you have clothes that are a step up from jeans and tennis shoes you probably should wear them just to be safe.

Once you get to the interview you should know the answers to some of the questions that will be asked of you. At your age they will mostly be standard questions revolving around who you are, what grade you are in, why you are looking for a job, whether you have any experience, what your grades are, and maybe even what subjects you like at school. These questions should be easily answered by you and you should have some basic responses at the tip of your tongue.

Don’t worry about the interview questions being too difficult as they will most likely be very simple and designed to help the manager get a feel of who you are. Jobs for 15 year olds usually involve simple tasks and thus they are looking more for someone who is trustworthy, will show up on time, and work hard rather than someone who has a specific set of skills.

In your job interview, it is important to do your best at remaining calm and giving good concise answers to the questions. Let the interviewer learn who you are and be as likeable as possible. Some jobs you may be trying to get may involve dealing with the general public and so a good or even great personality may be needed.

Even though the economy is really down now and it is really hard to get jobs for teenagers, you mustn’t appear desperate to get the job. You should never brag about the things you have done, but go over them factually instead if it is relevant. It is important that you try to exibit a calm and collected demeanor at all times and make the best case for you being hired. 

Remember, you will probably be one of several or many that are being interviewed for the job(s) and the hiring manager will probably ultimately go with a gut feeling. For this reason it is important that you do your best to look nice and present yourself as someone who can do the job well and can be relied upon. Once you have done that, all you can do is hope that luck is with you.
