I am asking this question on behalf of my girlfriend. She recently applied for a job at Macy's (a department store). After about a week, they wanted to schedule an over-the-phone interview, before doing an in-person interview. So they scheduled it, and she was nervous but I told her it would be fine. It wasn't. When they called the first time, they asked to clarify on how to spell her name. She spent about 15 seconds not saying anything, and then hung up the phone. After about a minute, they called her back, and I told her to say that the line got disconnected, in an attempt to recover the interview. They answered and proceeded on to the interview. Then they asked (and I'm paraphrasing here) if she uses technology. Again, she got real quiet, was like that for about 15 seconds, and then hung up the phone. They did not call back at that point.
We spent a couple of weeks training for the phone interview. I would call her from a random number at different points during the day, and ask some normal interview questions, and she was fine. It was only when it came to an interview that mattered that she wasn't able to do it.
So my question is, how can I help her get over this social/over-the-phone anxiety that she's experiencing?
