I get a lot of recruitment spam from India based companies. In fact it seems as though they've taken over the low end of the market. Typically they open with a vague description of a position that "matches your qualifications", then ask for a set of answers including number of years of experience in ten skills and my expected rate.

This approach to recruitment may work for some segments of the market, but it's pointless for me. I used to actually respond to such inquiries when the market was very slow and I was getting desperate, but they almost never followed up, so I stopped wasting my time.
