Practice. Practice. Practice.
It’s essential to spend time thinking carefully about your skills, accomplishments, and your answers to some common interview questions. Make sure to have your “tell me about yourself" response ready to go.
Practice looking in the mirror and answer your responses out loud. Have your friends conduct some mock interviews. You can even record yourself. This prep work will help you clarify your thoughts and make you much more comfortable during the interview.
