“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.

- 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.
