I did some free lance interviewing for one of these types of companies a few years ago. The theory is, get a bunch of well qualified senior technical types to conduct anonymous phone interviews and do a general technical screening.<p>In practice... it was very low paying, boring, and often irritating. There were some really unqualified people I had to interview and it was agonizing.<p>I don't see this model as working very well. I didn't work for the employer, so I couldn't really represent them or cut the applicant any slack. I could only ask them canned questions. I tried my best, but I have no idea whether the results were usable.<p>I wonder what kind of people these employers ended up getting, when they outsourced their interviewing process like this.
