When you're looking for a new career, you should consider working as a security professional. It's a stable and flexible job that can provide you with competitive pay. Plus, you'll have the opportunity to move around throughout your workday, which can fight the negative impact a sedentary lifestyle has on your health. If you'd like to get started in this exciting industry, review the following four tips to help you get hired:

1. Find a security class.

You don't need to go to school to become a security professional, but taking a class can help differentiate you from the competition. You can find classes available online which will teach you the basics of security work. Online courses are a great option for anyone who works full-time, since you can keep your current job while you brush up on your security knowledge in your free time.

2. Do your research.

Your interview is your opportunity to impress your potential employer. You want to make sure you sound well-informed about the company you're hoping to work at and about security work in general. Do your research before you show up to your interview. Learn a few things about the company, so you can discuss it in an intelligent and thoughtful manner.

3. Ask a few good questions.

During your job interview, there will probably be a portion toward the end where your interviewer asks you if you have any questions. This is an excellent chance to impress them. Have one or two relevant questions prepared. You can ask about the employee culture at the security company or about the tasks you'll be required to perform. Just make sure to listen throughout the course of your interview, since you don't want to ask something that's already been answered. Asking questions about the company itself is another great tactic you can use.

4. Dress nicely.

When you start work as a security professional, you'll likely be given a uniform to wear. This uniform will probably be fairly casual, to allow you to move around as necessary over the course of your workday. However, you should still dress up for your interview. Remember that you only have one chance to make a good first impression when applying for security jobs. Wear a button-down shirt and slacks, and make sure both are clean and pressed. It's better to be slightly overdressed than to be underdressed when it comes to a job interview.
