I’m about to have a phone interview any advice ?

When I'm anxious on the phone I do something with my hands, like twirl a string from my shorts around my finger, weird example I know but it helps me to focus. It helps release that nervous energy I guess. Also take a some deep breaths before and practice your answers to questions you think might come up so you can have an idea of what you might say in your head already. These are things I'd do/done, good luck!
