Clarify what 'calls' and 'product' refer to, then structure your answer by breaking down the user base and usage patterns. Use a top-down estimation approach, stating assumptions clearly and calculating step by step to arrive at a reasonable estimate.
Pro tip: Show your work and sanity-check your final number against known benchmarks (e.g., average calls per user per day for similar products) to demonstrate business acumen.
Ask clarifying questions to define 'calls' (e.g., voice/video calls) and 'product' (e.g., Google Meet, Google Voice, or a specific feature). Confirm whether it's global or a specific region, and if it's for all users or a segment.
Estimate the total addressable user base (e.g., Google Meet has ~100M+ daily active users). Break it down by relevant segments (e.g., consumer vs. enterprise, mobile vs. desktop).
Assume an average number of calls per user per day based on the product's nature. For example, a business communication tool might have 2-3 calls per user per workday, while a consumer app might have 0.5 calls per user per day.
Multiply the user base by the average calls per user to get a daily total. Adjust for factors like peak vs. off-peak usage, seasonality, or growth trends.
Compare your estimate to known industry benchmarks or internal data if available. State the final number with confidence, acknowledging the assumptions made.
