Nope. How long has this person been recruiting? Unless it's 10 years or more, I would be extremely skeptical (and if so, I'd still be somewhat skeptical). There are so many recruiters out there that are even more clueless than all the wannabe quants out there. But a large portion of them have a smart idea they undoubtedly learned from others, which is: spam everyone with lucrative seeming positions, hook one that manages to get through the company filters and gets the position, collect month or more of their salary. Just like the Viagra spam people, it only takes a few to make the whole enterprise worth it.
