Jeez, the most I ever got was called aside by the VP of Engineering on my last day to give him my opinion of their Diversity program ("since you're leaving, I figured you could be brutally honest with me"). Loved him for that, BTW :-)
But seriously, congratulations!
The negative effect of "fake diversity" is that it leaves everyone else wondering if the minority employees actually know what they're doing or if they were hired to make the company look good.
