It's amazing how short our memories are for all the companies 10 years ago bending over backwards to give those employees anything and everything they wanted.
A lot of my statement here is very generalizing but at the end of the day market forces really do dictate a lot of this. I keep seeing article after article from hiring managers about how they're FLOODED with applications. You can't be 'polite' to all those people, as most people don't have the attention span for all that. There are definitely 2 sides to this coin it just seems that from the side of the people wanting to be hired they just have no empathy for those doing the hiring.
