Applying for a new job can be nerve-wracking. You always hope the company calls you back. If you've been called to schedule an interview, you know how important it is to make a good impression. In an interview, your appearance counts. Here are four tips to help you impress your prospective employer and succeed in your job interview:

1. Get a haircut.

Hair that's long or unkempt can make an employer less likely to hire you. For your job interview, it's best to keep your hair neat and well-managed. If it's been a while since your last trim, it's a good idea to visit the barbershop for a haircut. Ask your barber for styling tips while you're there. They may be able to recommend a pomade or hair gel that can help you style your hair before your interview.

2. Groom your facial hair.

It's fine to have a beard or mustache, but make sure your facial hair is in good condition. A scraggly, messy beard can make it look like you don't pay enough attention to your personal hygiene. If you have a beard, get it cleaned up at the barbershop before your big day. A barber can trim it to a manageable length and neaten your edges. Having hair growing under your chin and on your neck can make you look unkempt, which is the last thing you want. Use beard oil to condition your beard for a healthy, natural shine.

3. Invest in a nice outfit.

When going for an interview, you should always dress for the job that you want. That often means dressing more nicely than you normally would. Choose your outfit based on the culture of the company you're applying to. If people there typically wear t-shirts and jeans to work, wear a nice pair of pants and a button down shirt. If they wear collared shirts and trousers, you should wear a suit and tie. You don't want to be too overdressed, but it's always better to err on the side of dressing too nicely; you definitely don't want to look shabby when you meet your potential boss.

4. Be confident.

Finally, remember to be confident when going to your interview. Study the company so you'll be able to answer their questions, and prepare a few questions for your interviewer as well. When you know you look good, you'll be able to project an air of confidence.
