The best way to calm your nerves is to research the organization you are interviewing with. Nothing impresses a manager more than a candidate that has taken the time to know the organization, its offerings and its employees. Research the people who will be interviewing you and their roles within the organization. The more prepared you are, the more confident you’ll be in responding to their questions.
Prepare everything ahead of time to avoid last minute distractions. Copies of resumes, clothes, directions should all be done prior to the interview day. These small distractions can frazzle anyone on the day of the interview.
Rehearse. Even if you're a seasoned candidate, it always helps to rehearse your answers prior to the interview. Stand in front of a mirror and try to answer the questions interviews are most likely to ask. You can practice your pitch, your posture and finally the quality of your answers as well. If not, rehearse with someone and ask them for feedback!
Smile - Nothing can disarm an interviewer more than a confident smile! It can put them at ease as well and boost your confidence too!
Normalize - try to present your best by sitting straight, and being confident. Try to think of the interview as a conversation, where two people are trying to get to know each other to see if there is compatibility. Remember, an interview is not a one way street. The interviewer should be able to impress you enough to want the job as well. So stand tall, smile and be confident!
