called my cell phone on feb 12  ~3:35. no message. been getting a lot of such called from unknown numbers since I started applying for jobs or visiting job sites; it may be that the job sites you are brought to from another known site are place to avoid.  I'm even seeing references , such as the name I put in an online application, in gmails.   Some numbers call 2 or 3 times a day, leave no message.

Won't stop calling

gotten several calls, no vm, since I started applying for jobs. other sites indicate a scam call

I get calls from this number several times a week. Will not leave a message though.

They seemed to have started after signing up on a Hospital Careers website.  A recorded voice announces "Hi this is Kelly, I see that you've recently been on a website of ours" (or something like that).  Then, there's a pause and "can you hear me ok?"  I've also received these from a phones numbers in Yellow Springs/Clifton  937-319-1927 , Enon 937-340-1906, Lewisburg 937-583-1927, N Lewisburg 937-612-2020.
