As a related question, how to filter out mediocrity. I mention this because your experience, which probably gels with many of us, shows companies should be applying some kind of "fizzbizz" test for these candidates.
For example, a simple question I would ask of business development is what technology (car, phone, public transport tickets, etc.) they've used today, and how would they improve it. If they can't walk through the problems and opportunities, they're probably not suited for a role where they'll need to be pitching ideas to potential partners.
