In short, he was the most arrogant, buzz-word filled SOB I ever had the displeasure of meeting,
After he finally got booted when people realized he didn't know a damn thing about technology I flat out asked the VP of engineering: "What did you ever see in him?".
He said: "You know, you're going to think I'm crazy, but he was exactly the same in the interview as he was around here daily, and I really thought that cockiness would mean he would take the lead on issues and be able to guide the younger guys".
So remember that kids, if you want to be seen as leadership material, thoughtfulness and pensiveness are not the way to go about it.
Just look at CTOs at companies you respect for further proof and see how many timid figures you find.
