What are my strengths and weaknesses as a salesperson? My strengths are prospecting, sales force, customer relations, retention management. I also am really good at building relationships. I build a rapport really easy. Weaknesses in the sales role, very tough to find weaknesses in sales due to the fact that I've had so many years experience doing it. As far as strengths, I've been outside sales, inside sales, relationship building. I've run the gamut when it comes to sales and the sales cycle.
