That experience is invaluable to anyone who can adapt and apply the learned mistakes to future work. Especially so if being applied to a startup environment. You have to be laser focused, gritty, willing fight 24/7/365 for years. This doesn't just apply to the founder/CEO it applies to anyone involved early stage, every day is just too mission critical and the entire team needs to be aware of the consequences. For the most part or most teams, you don't learn that at Google.
That's who i'd want on my team at least.
