Fifteen years ago I asked an outside vendor to help me and my team put together an assessment that we might be able to use to pre-screen wholesalers at the point of the interview. What I wanted was something that was custom designed.
While DISC and Myers Briggs are instructive, they are not specific to the craft of wholesaling.
The vendor undertook interviews with successful existing wholesalers that we employed as well as national sales managers and divisional sales managers within our firm.
