I'm sure I'm not the most experienced here, but I am an IT director in a global enterprise and have ten years experience managing an internal appdev group, as well as owning our messaging, collaboration, and content services platforms/org. If there's interest, I'd be happy to kick off an IAMA to facilitate Q&A from folks who might like to know more about how the vetting process tends to work in a large corporation, or things they might do to wedge their foot in the door.
If this would be useful or interesting, let me know and I'll post.
