Capgemini Manager interview questions

I discussed a demand forecasting project for a retail client, where I implemented an ensemble of time series models (ARIMA + XGBoost) to predict weekly sales at a store-SKU level. We integrated features like seasonality, promotions, and holidays. The model improved forecast accuracy by 18%, helping the business optimize inventory and reduce stockouts by 12%.

Questions were related to Process, People Management and Customer Handling.
