“The best risk management starts with a sound cost estimate.” – Anonymous
As a cost estimator, you can expect interview questions that assess your technical skills, attention to detail, communication abilities, and more. Hiring managers want to understand your experience and capabilities related to reading blueprints, using estimation software, applying quantitative methods, monitoring budgets, and contributing to the greater construction planning process.

When interviewing for a cost estimator role, make sure to discuss:

- Your analytical mindset and how you incorporate contingencies and cost implications of potential issues.
- Your collaboration abilities to work closely with managers, engineers, architects, and tradespeople.
- Your communication skills in presenting bid proposals or cost reports concisely.
I still remember one VP of Estimating telling me: “We can teach process and software, but we can’t teach attention to detail.” That advice has stuck with me throughout my career.
