Eight Estimator interview questions, and what the interviewer is thinking

1. What does a typical day as an estimator involve?

Why they ask: They want to check you understand the real workload and rhythm of a tender-driven role.

2. Talk me through how you would prepare a tender estimate from receipt of the documents to submission.

Why they ask: This is the core process of the role and shows whether you work methodically.

3. How do you carry out a quantity take-off, and which software and measurement rules do you use?

Why they ask: Accuracy of measurement drives price, so they need to see your method and standards.

4. How do you deal with subcontractor quotes, and how do you level them?

Why they ask: Subcontractor packages are often most of the price, so leveling quality matters.

5. How do you build up preliminaries for a project?

Why they ask: Preliminaries often decide whether a bid wins or loses money.

6. How do you price risk and opportunity in an estimate?

Why they ask: They need to see you do not simply hide risk in rates or ignore it.

7. You are two hours from a tender deadline and a key subcontractor has not returned a price. What do you do?

Why they ask: Tests how you handle pressure and incomplete information.

8. Tell me about a time you won a tender where your estimating made a difference.

Why they ask: Looking for evidence of impact and commercial insight.

A sample answer to question 1

What does a typical day as an estimator involve?

No two days are identical because it depends where we are in the tender cycle, but a typical day starts with checking the bid tracker for deadlines. I then work through the tender documents, drawings and specification for the package in hand and pick out the scope, risks and any gaps. Much of the day is quantity take-off, usually in software such as CostX or Bluebeam, then pricing items using rates from my database, supplier quotes and subcontractor returns. I chase subcontractors for quotes, level them so I am comparing like with like, and build up preliminaries, overheads and profit. There is also time spent writing tender queries, attending bid review meetings with the commercial director and checking the final submission against the instructions. Afterwards I try to feed back actual costs from live jobs so my rates stay realistic.

Common mistake to avoid: Describing it as just pricing from a rate book; Ignoring the deadline pressure and coordination
