“Salespeople and Engineers, what a dream it is they communicate together so well,” said NO ONE IN THE HISTORY OF THE WORLD! Salespeople have the reputation of being pushy, engineers the reputation of anti-social.
While there are some who fit those descriptions, for the most part the truth is much simpler.
They are both trying to get their jobs done.
For sales, their job requires conversations to move a deal along. For engineers, that requires alone time to think, calculate, draft, etc. Each one’s job interrupts the other.
Very few are bad people, we’re all just trying to get our job done.
