100 Forecasting Puller Interview Questions & Answers

  1. What is a forecasting puller?

    • Answer: A forecasting puller is a system or individual responsible for gathering and integrating data from various sources to create demand forecasts. They pull information from sales data, market trends, economic indicators, and other relevant sources to build a comprehensive forecast.

  2. Describe your experience with forecasting software.

    • Answer: [Replace with your specific experience. Example: "I have extensive experience using statistical forecasting software such as SAP APO, Demand Solutions, and Anaplan. I'm proficient in building and managing forecasting models, analyzing results, and communicating findings to stakeholders."]

  3. What forecasting methods are you familiar with?

    • Answer: I am familiar with various forecasting methods, including moving averages, exponential smoothing, ARIMA models, regression analysis, and qualitative forecasting techniques such as expert panels and Delphi method. I understand the strengths and weaknesses of each method and can select the most appropriate one based on the data and business context.

  4. How do you handle data inconsistencies or missing data in forecasting?

    • Answer: I address data inconsistencies by identifying the source of the error and correcting it if possible. Missing data is handled through imputation techniques such as mean imputation, median imputation, or more sophisticated methods like multiple imputation, depending on the nature and extent of the missing data. I always document my approach and justify my chosen method.

  5. Explain the concept of forecast error and how you measure it.

    • Answer: Forecast error is the difference between the forecasted value and the actual value. I measure forecast error using metrics such as Mean Absolute Deviation (MAD), Mean Absolute Percentage Error (MAPE), Root Mean Squared Error (RMSE), and Mean Squared Error (MSE). The choice of metric depends on the specific needs of the business and the characteristics of the data.

  6. How do you identify and address outliers in your data?

    • Answer: I identify outliers using various statistical methods, such as box plots, scatter plots, and Z-score analysis. Once identified, I investigate the cause of the outliers. If they are due to errors, I correct them. If they represent genuine events, I may need to adjust the forecasting model or treat them separately.

  7. How do you communicate your forecasts to stakeholders?

    • Answer: I communicate my forecasts clearly and concisely using visualizations such as charts and graphs, as well as written reports. I explain the methodology used, the assumptions made, and the potential uncertainties involved. I also tailor my communication to the audience's level of understanding.

  8. What are the key performance indicators (KPIs) you use to evaluate forecast accuracy?

    • Answer: Key KPIs I use include MAPE, RMSE, Bias, and forecast coverage. I also consider qualitative factors like stakeholder satisfaction and the impact of the forecast on business decisions.

  9. How do you handle seasonality in your forecasts?

    • Answer: I handle seasonality by incorporating seasonal indices or using time series models that explicitly account for seasonal patterns, such as seasonal ARIMA models or incorporating dummy variables in regression analysis.
