How to Prepare for an AECOM Interview: Process, Questions & Tips

What to Expect from the AECOM Hiring Process

AECOM is a global infrastructure and engineering firm that recruits across disciplines including civil engineering, project management, environmental consulting, and corporate functions. Their hiring process typically follows a structured, multi-stage format common to large professional-services employers.

Whilst exact stages vary by role, region, and seniority, candidates generally move through: an online application and CV screening, one or more online assessments (such as a numerical or verbal reasoning test), a video interview or telephone screen, and one or more competency-based or technical interviews. For graduate schemes, assessment centres are common at the final stage.

• Online application and CV/cover letter review
• Psychometric or situational-judgement tests
• Recorded video interview or telephone screen
• Competency-based interview (panel or one-to-one)
• Assessment centre (primarily for graduate or early-career roles)

Online Assessments: What You Need to Know

Many large engineering and infrastructure employers, including AECOM, use online assessments to screen candidates efficiently at volume. These commonly include numerical reasoning, verbal reasoning, and situational judgement tests. You may be asked to complete these under timed conditions shortly after submitting your application.

Numerical reasoning tests typically present data in tables or graphs and require you to draw accurate conclusions quickly. Verbal reasoning tests assess your ability to interpret written passages. Situational judgement tests present workplace scenarios and ask you to choose the most appropriate response — these often reflect the company's values around safety, collaboration, and integrity. Practise under realistic timed conditions beforehand, as familiarity with the format matters as much as raw ability.

• Use free or paid practice platforms to build speed and accuracy
• Read questions carefully — SJTs reward considered, values-led answers
• Ensure you are in a quiet space with a reliable internet connection
• Don't guess randomly on numerical tests — work through your logic

The Video Interview Stage

For many roles, AECOM uses a one-way recorded video interview — the kind where you record answers to pre-set questions without a live interviewer. You are typically given a short preparation window before recording each response. Questions at this stage are usually a mix of motivational questions ('Why AECOM?', 'Why this role?') and introductory competency questions.

Performing well on a recorded video interview requires practice that many candidates skip. You need to speak clearly, hold your eye line with the camera rather than the screen, and structure your answers within a strict time limit — often 60 to 90 seconds per question. Recording yourself answering out loud is far more useful than reading notes silently. ScreenReady is built specifically for this format: it simulates timed, one-way video interviews and gives you AI feedback on structure, clarity, and delivery so you can sharpen your responses before the real thing.

• Prepare a concise, specific 'Why AECOM?' answer that references their projects or values
• Structure even short answers: a brief context, your point, a concrete example
• Check lighting, background, and audio before you begin
• Dress professionally — first impressions count even on a recording

Competency Interview Questions and How to Answer Them

Competency-based interviews are standard across infrastructure and professional-services firms. Interviewers ask behavioural questions designed to reveal how you have acted in past situations, on the basis that past behaviour predicts future performance. AECOM's core values — such as safety, inclusion, integrity, and collaboration — tend to inform the competencies assessed.

Use the STAR method to structure every behavioural answer: Situation (set the scene briefly), Task (explain your specific responsibility), Action (describe what YOU did, not what the team did), Result (quantify outcomes wherever possible and reflect on what you learnt). Aim for answers of roughly two to three minutes in a live interview.

• Teamwork and collaboration: 'Tell me about a time you worked across different disciplines or teams to deliver a project.'
• Problem-solving: 'Describe a situation where you identified a technical or operational problem and found a solution.'
• Communication: 'Give an example of when you had to explain a complex idea to a non-technical stakeholder.'
• Safety or ethics: 'Tell me about a time you raised a concern about risk or quality, and how you handled it.'
• Resilience: 'Describe a project that didn't go to plan. What did you do and what did you learn?'

A STAR Answer Example for AECOM

Question: 'Tell me about a time you identified and solved a problem on a project.'

Situation: 'During a drainage design project in my final year placement, I noticed mid-programme that our stormwater calculations had been based on an outdated rainfall intensity dataset.' Task: 'As the junior engineer responsible for that section of the report, I needed to flag the issue, quantify the impact, and recommend a path forward without derailing our submission deadline.' Action: 'I cross-checked three data sources to confirm the discrepancy, prepared a concise risk summary for the project lead, and proposed two revised design options with indicative cost implications. I also drafted updated calculations overnight so the team had something to review immediately.' Result: 'The project lead approved the revised approach within a day. We submitted on time, the revised design was adopted, and my line manager cited this as a key example of professional initiative in my end-of-placement review.' This answer is specific, action-led, and ends with a concrete, verifiable outcome — exactly what AECOM interviewers are looking for.

Technical Interviews and Assessment Centres

For engineering and technical roles, you may face a technical interview in addition to — or combined with — the competency stage. Interviewers will probe your discipline knowledge, design standards awareness, and problem-solving approach. Be honest about the limits of your knowledge and show how you would find an answer rather than bluffing. Interviewers at this level value intellectual rigour and professional humility.

Assessment centres, more common on AECOM's graduate programmes, typically combine group exercises, case studies, and individual presentations. In group tasks, balance contributing your own ideas with actively listening to others and helping the group reach a decision — assessors watch process as much as outcome. For case studies, structure your analysis clearly and acknowledge trade-offs. Prepare a short personal presentation if asked, keeping it structured: context, key points, clear conclusion.

• Revise relevant standards and codes for your engineering discipline
• Be ready to talk through your degree or work projects in technical detail
• In group exercises, show active listening — don't dominate or go silent
• For presentations, practise out loud at least three times before the day

Final Preparation Tips: The Week Before Your AECOM Interview

Thorough preparation in the days before your interview will separate you from candidates who rely on improvisation. Research AECOM's major recent projects (their newsroom and LinkedIn page are good starting points), understand their stated values and strategy, and connect these to your own experience. Have two or three strong STAR stories ready that you can adapt to different questions.

Practise answering questions on camera under time pressure — not just in your head. ScreenReady lets you run through timed video responses and receive structured AI feedback, which mirrors the actual conditions of a recorded video interview. Prepare three or four thoughtful questions to ask the interviewer, focused on the team, the project pipeline, or development opportunities. Finally, confirm logistics the day before: the platform or location, your interviewer's name, and any ID or documents required.

• Research two or three AECOM projects relevant to your target service line
• Prepare your 'Why AECOM?' and 'Why this role?' answers specifically
• Have five STAR examples ready covering different competency areas
• Test your tech (camera, microphone, internet) at least 24 hours before
• Prepare considered questions that show genuine curiosity about the role
