My first instinct was to jump straight into rollout phases but I kept second-guessing whether they wanted execution mechanics or the product reasoning behind the change.
Start by clarifying the goal of the change—whether it's to reduce accidental likes, declutter the UI, or test user engagement—and then outline a structured plan that includes hypothesis, metrics, cross-functional alignment, and a phased rollout with A/B testing. Emphasize the importance of data-driven decision-making and user feedback loops to validate the change before full-scale implementation.
Pro tip: Frame the change as an experiment with clear success metrics (e.g., like rate, accidental likes, user satisfaction) and propose a reversible rollout to mitigate risk. Show that you understand Meta's culture of rapid experimentation and learning from failures.
Ask clarifying questions to understand the 'why' behind the change—e.g., is it to reduce accidental likes, simplify the interface, or increase engagement with other actions? Formulate a testable hypothesis, such as 'Hiding the like button will reduce accidental likes without significantly decreasing overall like rate.'
Identify primary metrics (e.g., like rate, accidental like rate, user engagement) and guardrail metrics (e.g., overall time spent, user satisfaction, support tickets). Ensure metrics are aligned with broader company goals and can be measured accurately.
Engage design, engineering, data science, and marketing teams early to assess feasibility, effort, and potential risks. Secure buy-in by communicating the hypothesis, expected impact, and rollout plan, and address concerns about user backlash or technical debt.
Implement the change as an A/B test with a small percentage of users, ensuring proper randomization and sample size. Monitor metrics in real-time and be prepared to pause if guardrails are breached.
After sufficient data, analyze the impact on primary and guardrail metrics. If positive, plan a gradual rollout with ongoing monitoring; if negative, iterate on the design or abandon the change, documenting learnings for future experiments.
