I've known all 3 of the enumerated types. I'd suggest a 4th to add in. - The humble one, who helps mentor their colleagues to be better at what they do. They do this by helping provide critical insight at important junctures. By not attempting to grab the spotlight, but instead shine praise upon their colleagues. These are people who help everyone get better. They are out there. While the first 3 are the loudest and most annoying, this 4th type is rarely self-identifying, often self-deprecating as they don't crave attention.
