The costs that are involved when you hire sales reps that do not work at can work out to be worth as much as six times the base salary of that person and this is why you need executive search companies to help you. Sadly, of the professional sales people in North America, 40 percent will not hit their quotas, 22 percent will prove to be untrainable, and just 10 percent will actually provide your business with a return on investment, which is why you need executive search companies to help you find more people in that 10 percent . An executive search firm will know exactly what to look for based on your needs so that you get an exemplary candidate.
