Introduction
This question is crucial for understanding your analytical skills and how you approach uncertainty in project estimation, which is vital for an Estimation Manager.
How to answer
What not to say
Example answer
“In my role at SNC-Lavalin, I was tasked with estimating the costs for a large infrastructure project with only preliminary designs. I gathered insights from past similar projects and consulted with our engineering team to understand potential challenges. I employed a parametric estimation method, considering both direct and indirect costs. My initial estimate was within 10% of the final costs, and through effective communication, I managed stakeholder expectations throughout the project.”

This question is designed to evaluate your approach to accuracy and validation in cost estimation, which is crucial for minimizing risks and ensuring project success.
How to answer
What not to say
Example answer
“To ensure accuracy in my estimates, I follow a structured process that includes detailed data analysis and reviewing past project costs. I utilize estimation software like Primavera to assist in calculations and then conduct peer reviews with my team to catch any discrepancies. For instance, in a recent project, my validation process revealed that we had underestimated labor costs by 15%, allowing us to adjust our estimates before finalizing them. Tracking our estimation accuracy has helped us improve our processes over time.”

Example answer
“During my internship at SNC-Lavalin, I was involved in a bridge construction project where I estimated costs and timeframes. I used parametric estimating based on historical data from similar projects, which allowed us to predict costs accurately. By collaborating with senior engineers and using software like Primavera P6, we reduced the initial budget estimates by 10%. This project taught me the importance of cross-team collaboration and continuous learning in the estimation process.”

Introduction
This question evaluates your problem-solving skills and ability to adapt when facing discrepancies, which is essential in estimation roles.
How to answer
What not to say
Example answer
“If I encounter discrepancies between my estimates and actual costs, I would first perform a root cause analysis to identify the reasons behind the differences. For instance, in a recent project at my university, I noticed our estimates were lower due to fluctuating material costs. I presented my findings to the project supervisor, which led to a review of our estimation methods. By documenting these lessons, I ensured we adjusted our future estimates to account for market variability, improving our accuracy by 15% in subsequent projects.”
