Doing well in a job interview is as much about mental preparation as anything else. A person who comes into an interview composed, relaxed and sharp is more likely to get the job than someone who comes into the interview nervous, tense and fidgety, even if they have a better resume.

Here are 5 ways to mentally prepare for your job interview.

Get Some Exercise Beforehand

Exercise gets the blood flowing through the body and burns up a lot of the anxiety you may be holding. It releases endorphins, which further relieves stress.

It helps relax muscles and creates more of a sense of aliveness and vitality. It'll help you create the impression that you'll bring a lot of energy to your new job.

Write Down Questions that may be Hard to Answer 

Create a list of questions that you think would be difficult for you to answer.

For example, if you have gaps in your employment, write down several questions that your interviewer might ask you. If you have a specific skill that you're lacking, write down questions that the interviewer might ask about that.

Then construct the perfect answers to those questions. The idea isn't to rehearse specific lines, but to mentally get yourself to release whatever insecurities you had about any weaknesses you may have.

Write Down Why You're the Perfect Candidate

You don't just need to sell the interviewer that you're the perfect candidate; you need to sell yourself as well.

You need to be able to look in your interviewer's eyes and know for a fact that they're going to be better off hiring you than anyone else.

Write down why you are the best for the position and reinforce that belief in yourself. You must first believe in yourself before you can convince anyone else.

Dress Sharp

Dress sharp and professional for your interview. Look at yourself in the mirror and give yourself a nod of approval. 

Going into an interview knowing that you look good and look professional can make a big difference on how you hold yourself and present yourself.

Mentally Prepare Through Imagination

In his book "psycho-cybernetics," Dr. Maxwell Maltz invented a technique where one visualizes themselves succeeding in whatever it is they want to endeavor.

He's perhaps the first person to invent this kind of systematic visualization. Since then, thousands of coaches have taken up this kind of success visualization.

Here's how it works: Visualize yourself in the first person in the interview. Feel yourself relaxed and confident. Imagine yourself hitting it off with the interviewer and getting the job.

Do this daily throughout the week leading up to the interview. By the time you actually do the interview, it'll be like you've already been through the process before.

These five tips should help support you in getting into the right mindset to successfully ace your interviewers.
