I may be one of the folks who work at a FANNG company, but honestly I have seen almost none of this in my years there. On the contrary, I have seen mostly experts who are thoughtful, bright and open to sharing their knowledge and experience. Some can improve interpersonal skills, but so could the populace at large. I have seen more, nicer, smarter and engaging people here than almost any other genre of business I have worked at, e.g. Wall Street, tech startups, etc.
