For you, what is the difference between a manager that has 5 years of experience and one that has 10 years of experience . Which to recruit and why?

It depends on the Events & Experience during those years.

"years of experience" tell you very little about a candidate's likely performance.

Remember that only a fool learns from experience.   The wise learn from the experience of others.

Hired 10 years, because practice make a man perfect.
