Behavioral Styles Test

A company wants to hire 5000 salespeople – but why?

2000 drop out before completing training, and another 2000 drop out during the first 90 days in the field. Another 500 drop out during the first 6 months, and at the end of the year they only have 500 of the original 5000 standing.  What would it be worth to them from a cost, time, resources and practicality standpoint for us to simply identify, in advance, the final 500, before anyone is hired?
