A seasoned recruiter held a lecture about hiring executives at a conference. She presented some interesting observations - when hiring, recruiters (judged by ad descriptions) seem to be looking for psycho- and sociopaths.
If you don't fit the psychological profile, you are in for a helluva ride. I took a CISO role in a startup, working with very young executives - jaw-dropping experiences, almost every day. But it was an invaluable life lesson working there.
