It's wrong that a CEO would make such a statement, and it's downright tragic no one would call him on it. Age is not a hiring factor that is good for your company, you miss out on a lot of people who have energy, are curious and creative, and can get things done. I've had the pleasure of working with 50+ who are as energetic as 22 year olds but 100x more effective.
Good work knows no age.
