← Instacart Interview Insights
I spent too long on the metrics layer and not enough time thinking about who actually uses this dashboard.
Start by clarifying the dashboard's primary users (e.g., operations managers, supply chain analysts) and the key decisions it should support, such as reallocating shoppers or adjusting incentives. Then, structure your answer around a metrics-driven framework that covers demand forecasting, real-time monitoring, and actionable levers, while highlighting Instacart-specific factors like batch efficiency and shopper utilization.
Pro tip: Emphasize that the dashboard should not just predict demand but also recommend actions, and mention the importance of measuring prediction accuracy (e.g., MAPE) to build trust. Also, consider the trade-off between granularity and usability—too many metrics can overwhelm users.
Identify who will use the dashboard (e.g., regional managers, central ops) and what decisions they need to make, such as adjusting shopper incentives or reallocating resources. This ensures the dashboard is tailored to actionable insights.
Select metrics like demand forecasts, shopper supply, batch fill rate, and shopper utilization. Combine historical data, real-time signals (e.g., order volume), and external factors (e.g., weather, holidays) to predict demand.
Incorporate predictive models (e.g., time-series, ML) for demand at granular levels (zone, time slot) and real-time monitoring of supply-demand gaps. Include accuracy metrics to validate predictions.
Provide recommendations or automated triggers for actions like surge pricing, shopper incentives, or shift adjustments. Set thresholds for alerts when demand-supply mismatch exceeds acceptable levels.
Start with a MVP focusing on critical metrics and expand based on user feedback. Plan for continuous improvement by tracking dashboard usage and prediction accuracy over time.
