Product owners hold the backlog: deciding what a delivery team works on next, writing the stories, and being available to answer the questions that arise mid-sprint. In Indian organisations the title usually implies delivery ownership rather than market strategy, which distinguishes it from product management. It is reached after several years as a business analyst, engineer or consultant. Certification in agile frameworks is common on CVs and rarely decisive; what employers examine is whether you have shipped and made prioritisation calls under pressure.
