How to use this page
Don't memorise answers. For each question, read what the interviewer is looking for, then practise answering out loud in your own words with a real example. The notes describe strong answers and common red flags — they are for your prep, not a script.
BOQ Preparation
1 questionWalk me through how you prepare a Bill of Quantities from drawings.
IntermediateWhat the interviewer is looking for: Strong answers take off quantities systematically per a standard method, itemise clearly, and cross-check against drawings. Careless take-offs that miss items are a red flag that leads to cost overruns.
Estimation and Costing
1 questionHow do you approach estimating and costing for a project?
AdvancedWhat the interviewer is looking for: Look for building up costs from quantities, current rates, wastage, and overheads, with contingency for uncertainty. Guessing costs with no basis is a red flag.
Rate Analysis
1 questionHow do you carry out a rate analysis for a work item?
IntermediateWhat the interviewer is looking for: Strong candidates break the rate into material, labour, plant, and overheads with realistic productivity. Copying rates without understanding them is a red flag.
Attention to Detail
2 questionsWhy is precision in measurement and quantities so important in QS work?
BasicWhat the interviewer is looking for: Look for recognising that small errors scale into large cost differences, and using careful checking. A casual attitude to measurement accuracy is a red flag.
How do you keep accurate records to support valuations and final accounts?
BasicWhat the interviewer is looking for: Look for disciplined documentation of measurements, variations, and correspondence. Poor records that cannot support a claim are a red flag.
Excel
1 questionHow do you use Excel to build reliable, checkable cost workings?
BasicWhat the interviewer is looking for: Strong answers use structured, formula-driven sheets with checks and clear assumptions. Manual, error-prone spreadsheets are a red flag.
Tendering
1 questionHow do you manage the tendering process to get competitive, comparable bids?
IntermediateWhat the interviewer is looking for: Look for clear tender documents, fair evaluation on a like-for-like basis, and spotting abnormal bids. Comparing bids with different scopes as if equal is a red flag.
Contract Management
1 questionHow do you handle variations and claims during a project fairly?
AdvancedWhat the interviewer is looking for: Strong candidates value variations per the contract, keep records, and assess claims objectively. Poor record-keeping or accepting claims without substantiation is a red flag.
Cost Control
2 questionsHow do you control cost as a project progresses?
IntermediateWhat the interviewer is looking for: Look for tracking committed versus budget, forecasting final cost, and flagging overruns early. Only discovering an overrun at the end is a red flag.
How do you handle pressure to certify more work than has actually been completed?
IntermediateWhat the interviewer is looking for: Strong answers certify only measured, completed work and resist pressure to over-certify. Certifying uncompleted work is a serious integrity red flag.
Negotiation
1 questionHow do you negotiate rates or a settlement with a contractor?
IntermediateWhat the interviewer is looking for: Strong answers are prepared with data, aim for fair outcomes, and protect the client's position. Being unprepared or purely adversarial are red flags.
Quantity Surveying
1 questionThe BOQ quantity differs from what is built on site. How do you handle it?
AdvancedWhat the interviewer is looking for: Look for measuring actual work, reconciling with the contract, and documenting the variation transparently. Ignoring the discrepancy is a red flag.
AutoCAD
1 questionHow do you read drawings to extract quantities accurately, including with AutoCAD?
BasicWhat the interviewer is looking for: Strong candidates interpret drawings correctly and use tools to measure precisely, cross-checking. Misreading drawings leading to wrong quantities is a red flag.
Behavioural & role-general
2 questionsTell me about a project where you helped control costs or resolve a dispute.
BasicWhat the interviewer is looking for: Look for a concrete contribution, sound method, and a fair outcome. Vague involvement with no result is a red flag.
How do you balance protecting the client's budget with treating contractors fairly?
IntermediateWhat the interviewer is looking for: Strong candidates are firm but fair, applying the contract objectively. Being either a pushover or unreasonably adversarial are red flags.
