What this question tests
Goal setting for an internal Meta product against a real competitive backdrop of Zoom, FaceTime, and Google Meet.
How to approach it
- State the objective: make Messenger video calls the default choice for personal video calling within Meta's ecosystem.
- Set the primary goal as weekly video call minutes among Messenger users, since it reflects habitual real usage, not just trial.
- Add a quality guardrail, call drop and connection failure rate, since video call reliability directly drives whether people return.
- Add a competitive framing goal, share of video calling time relative to other apps a user has installed, if that data is obtainable, otherwise use self reported survey data.
- Segment by group versus one on one calls, since group calling is a differentiator Messenger can push against FaceTime.
- State you would confirm whether the focus is retention of existing callers or acquisition of new video callers.
What a strong answer includes
- Frames goals around Messenger's actual competitive position against FaceTime, Zoom, and Meet, not generic video metrics.
- Separates group and one on one calling, since group calling is a real differentiation opportunity.
- Includes a reliability guardrail, since dropped calls are the fastest way to lose habitual video callers.
Common mistakes
- Setting goals with no reference to competing products users could switch to instead.
- Ignoring call quality guardrails and focusing purely on volume metrics.
Likely follow-up questions
- How would you measure whether users are choosing Messenger over FaceTime specifically?
- What would you prioritize if group calls are growing but one on one calls are flat?
