I can come up with many 3-sets of Microsoft products roughly in the same areas as Calbucci did.
OTOH, once about every 6 months or so someone from Microsoft recruiting calls me. At first, I told them right away I'm not interested (I had enough contact with MS in the late 90's). Now I just let them go on. It usually takes them a couple weeks to google my name and conclude I wouldn't be a good fit.
