the same thing has just happened to me. by voicemail saying she was looking at my resume and she also mumbled her name & didn't give a company name or info and when she hung up, could still hear talking in the background. I didn't reply for I was scared and she called back again, and I still couldn't understand her. and again could hear talking in the background.  I called back after 5 to see if there was a afterhours voice mail and a person answered and it seemed to be a private number.

I have received two calls as well and have yet to return them. When I've received other calls which seemed like scams they only called once. The repeated calls are throwing me off.

Same thing is happening to me. She has called twice. I have not called back due to fear of scam.

I received a voicemail from this number, referencing my resume on the CalJobs site.  The caller mumbled her name, and did not give a company name, or any info on the open position.  It smelled like SCAM.  They asked me to call back at a slightly different number 951-515-9051, and when I did, it was clearly a wrong number.  Odd.
