I had a phone interview scheduled for 10:30 am today with the recruiter for a huge insurance company about a job application I'd sent in. The recruiter was the one who picked the day and time, and gave me her phone number to call. When I called today, I got her voicemail (saying she'd be out the week of Labor Day, almost two months ago). I left a voicemail for her requesting a call back. I waited next to my phone, with all my information nearby, for 20 minutes, but she never called back. It's been about an hour and a half now. Should I try calling her again? Or should I assume that something has come up and she'll get back to me?
