I submitted several applications to Client Manager positions in several locations, and got called by HR representatives for initial screen interviews for 3 of them (over a period of a few weeks). The first arranged for a written test at a nearby Nielsen location, which I learnt I passed after checking on the applicant website. There was a bit of a delay thereafter - it turned out that particular client couldn't decide how they wanted to proceed, or had some issues with my background.
In the interim, I was contacted by the other two recruiters, one of whom set up a hiring manager interview for me. After I had made non-cancellable travel arrangements, they decided to make it a phone interview, but relented when I explained the situation. At the interview it became clear though that I didn't have much of a shot, because the hiring manager was looking for someone with more experience in using Nielsen products.
My impression was that the hiring managers were looking for a 100% candidates, while the recruiters were much more adept at spotting longer-term potential. Everyone was very professional, and at least one of the recruiters seemed to go out of her way to be my advocate.
