I have personally seen scores of people employed to senior and executive opportunities whos resume is a total joke. 6 months here, year there, 3 months somewhere else, etc. having worked with and under such people so many times for 6-12 months before they inevitably move on, I am not at all impressed.

But then, every time, mega corp pas them a 6 fig sign on with gauranteed bonus, 2 levels higher than their last role, so what would I know.
