This is a suspicious recruiting firm calling up stating they are from a certain company and are looking to fill a contract position in a large city. In my case, they called up first from another line number stating they were from Microsoft and that they were wondering if I was interested in a contract position in the Manhattan area. They called up again later in the day stating that they were from another company with another recruiting position in Manhattan. They had my name both times and I stated I had full-time work and they were no longer interested.
