Alright, this is really funny. Do 10 people each with 4-year experience really add up to "40-year experience"? I don't think so. I think this is just kind of a joke.
What would you think if Google (now Alphabet) said their management team had over 100 years of experience? (not carefully calculated, but you can do the math if you like :))
They should be more honest than using such gimmicks.
