Everyone wants to make the best impression possible for when they enter a job interview in the security industry. You want to come across as confident, trustworthy, and easy to work with. Nobody is going to want to spend their work week with someone they can't get along with, let alone someone they have trust issues with. You want to demonstrate that you are seeking an opportunity to display your skills, and have a true passion for the industry. While you will be asked many questions, and have a natural temptation to try and cover every single base, the most important thing is to maintain your poise, and stay focused. Avoid these three negative characteristics:
You might be nervous in an interview, but you don’t want to show it. It's understandable that you will feel pressure, because you want a good job, but just remember, they wouldn't have called you in for an interview if they didn't already think you might be a good candidate for the job. You should be proud of your past accomplishments, and let that fill you with the confidence you need to win over the respect of the person interviewing you. If you are nervous, it might be helpful to have someone you trust conduct a mock interview with you. This may help you eliminate any stuttering or searching for the right answers. The more practice you have, the more relaxed you will become, and may come up with some even better responses to potential questions than you anticipated.
Ideally you will be able to display confidence in yourself by speaking clearly, and displaying knowledge of the industry, and the company itself after having done some research. However, you don’t want to appear arrogant. There is a fine line between someone who is seasoned, and someone who is just plain over-confident. Nobody is going to want to hire someone who feels the work is below them. If you have more than enough experience, that's great, but don't let it make you come off as arrogant. As there is a fine line between being seasoned and arrogant, there is also a fine line between being knowledgeable and presumptuous. Never, under any circumstances, offer advice on how the company should conduct is business, or critique the protocols the company has in place. Also, don’t correct the interviewer, or ask probing questions. You are the one being interviewed, and it is not appropriate for you to turn the conversation into an interrogation.
Being Too Available
It is already understood by the interviewer that you are ready and able to take the job if it is offered to you. However, displaying desperation is a red flag. You want to make yourself seem busy and in demand—that you could walk away from the table if need be. While you want this employer to hire you, you do not want to appear like you are hovering over the phone waiting for it ring! Just be mindful of going overboard on enthusiasm, as the too-available person will ask to start tomorrow, presumably because they have nothing better to do, or they were dismissed from their previous job. Also don’t talk about working on your job search, even if that’s all you’ve been doing. Don't let the employer think you are desperate for work, as it may hurt your chances at negotiating suitable compensation. Let the process work itself out, send a thank you note for the interviewer's time, and hope for the best.
