Online scam
I've gotten multiple interviews through SnagAJob.com. Kohls, Sears and some waitress positions. As for them giving out phone numbers. Back when I first made my account, I did get a phone call from a university, but I told them I was already enrolled somewhere. It's been 3 years now and I haven't been bugged since. So, I'd say, if you got spammed, it's just bad luck. It doesn't happen to everybody. I have friends who use the site too and they've never complained. It's definitely not a scam.
