Some Indian lady that I could hardly hear, she said my name and asked if I was available for full time work, when I said yes, she replied with I am calling from a company (could hardly her her at this stage, all I got was ASX) and then she asked me some questions (all of the information listed on my resume so I don't know how she got my number. definitely not through seek where I have a profile & resume publicly listed for employers to view) .
After a while I gave up repeating myself & hung up, I did a search and there is no business listed with this number. Sounds like a job offer that you would get in you e-mail spam folder.
