Ventajas
Pay that was offered was in the top quartile of industry. Unfortunately actually getting the promised pay out of them was problematic.
Desventajas
Firm reneged on the terms and conditions of a duly executed job offer. Bullies are promoted while top performers are bullied because they make the bullies look bad. This company will spend more money on lawyers to defend its mistakes in HR rather than actually admit them, make a few changes, and move on.
