Interview anxiety can be a bit of a set back for how well you present yourself in front of your future organization. There is nothing most of us fear more than being judged, but unlike other issues, this one is curable! There are several strategies you can try to improve how you feel before and during your interview.
If all else fails, remember to smile, breathe, speak slowly and make eye contact.
You're okay, or at least you will be. There are some small things you can do that can have a major impact on your comfort level. The first thing to consider is the location of the interview. Whether it is in person or virtual it is always good to do a dry-run so you are comfortable with the route or area where you will be going to the interview. Even if the interview is virtual you want to check the camera, audio and background scene. Comfortable and appropriate clothing as well as a thorough understanding of how your skillset can meet the goals of the organization also help you decompress and release anxiety.
Make sure everything is in order. Prepare and then prepare once again. Carry a copy of your documents with you and make sure you know a lot about the position you are interviewing for and the mission of the organization. You also want to make sure you have a way to take notes if needed.
Can you imagine that what you eat and drink before an interview matters? Whatever you consume can have a positive or negative effect on how you think and act. Although coffee seems like a good source of energy, it can intensify your already stretched nerves. Also, alcohol to take the "edge off" should be avoided right before an interview. Try and eat a small meal (big meals can make you sluggish) right before you go in so your energy levels are up and you don't have to be concerned about any "hunger growls".
