It tells me the leadership of those companies don't understand sales performance. :)

Sales people have the greatest jobs really! They either perform or they don't.. Its easy to measure and easier to take action.

Sales people, assuming commission is a large portion of their compensation as is common, are the absolute easiest to measure -"Show me your w2 form from your last job".

That isn't how it works.

What if the person had a compensation package which paid really well for selling a product which could be sold by over promising? Their W2 would look awesome but the company would be screwed. I would be most cautious of business people leaving a job with a strong w2. Also it is important to see relative performance. What if they are making 100k and their coworkers are bringing home 500k? Are they still good then?
