Ask HN: What's your story of becoming a Product Owner?

Hi HN!

My wife is looking into getting a job in IT. One of the roles that she thinks can fit her is a Product Owner (PO). She doesn't have any relevant training and her background is in academia (chemistry), so it's a totally new area. I would love to hear your success stories of becoming a PO. What is your background? What kind of training have you done? Where would you recommend to start from?
