How would you run the first 90 days after taking over Messenger

Problem Statement Description

Product context: Meta is a social technology company; its products include Facebook, Instagram, WhatsApp, Messenger, Threads, Quest, creator tools, and ads.

You have just taken over Messenger at Meta and need to explain how you would run your first 90 days as the product leader. The focus is on execution: how you would quickly understand the business, users, product health, team dynamics, and near-term risks while creating momentum without disrupting a large-scale messaging platform.

Messenger serves many user groups, but for this scenario, pay particular attention to community admins who rely on messaging to coordinate groups, manage conversations, keep members safe, and sustain engagement. Their workflows may involve onboarding members, moderating discussions, broadcasting updates, handling abuse, and moving between Messenger and other Meta surfaces.

Your plan should account for Messenger’s role in Meta’s broader ecosystem, including the social graph, network effects, ads and creator-adjacent opportunities, privacy and safety expectations, and competitive pressure from platforms such as Apple, Discord, Snap, TikTok, and YouTube. The interviewer is looking for how you structure the transition, not for a single feature idea.

The experience should consider:

- How you would diagnose the current state of Messenger across product performance, user needs, team health, and strategic priorities

- Which stakeholders you would meet early, including engineering, design, data science, integrity, privacy, policy, monetization, marketing, and leadership

- How you would identify the most important community-admin workflows, pain points, and operational risks

- How you would sequence the first 30, 60, and 90 days across learning, prioritization, execution, and communication

- What operating cadence you would establish for reviews, decision-making, dependency management, and accountability

- How you would define go/no-go criteria for near-term launches, experiments, or roadmap changes

- How you would manage launch risk, rollback plans, incident response, and safety issues at Messenger scale

- How you would communicate priorities and trade-offs to the team and senior leadership

The goal is to present a clear 90-day operating plan that shows judgment, prioritization, cross-functional leadership, and execution discipline in a high-scale consumer messaging environment.
