Few people start their career as a PM; common entry points include moving from engineering, design, customer support, business analysis, or founding a small product of your own, since each builds a different, useful lens on the product. Because few companies hire PMs with zero prior product experience, aspiring PMs often build a portfolio through side projects, writing detailed case studies of how they would redesign or improve an existing product (a format widely used and well-documented online), or taking on informal product responsibilities within a current role. Many PM interviews include a product sense case study, where a candidate is asked to design or improve a product live, and these are evaluated less on the exact answer and more on structured thinking: clarifying the goal, identifying the target user, generating options, and prioritizing based on reasoned trade-offs. As with the other tracks in this program, product work is evaluated on judgment and communication, not physical location, making it accessible to remote candidates who can demonstrate real product thinking.
