Our candidates report that AECOM is looking for more than a polished business analyst narrative — they want people who can speak credibly about the substance behind infrastructure and sustainability decisions. A recurring theme is that the questions are grounded in real-world development tradeoffs, from embodied carbon versus the circular economy to what makes a sustainable community viable. That tells us the interviewers are listening for practical judgment, not just familiarity with buzzwords.
What makes this process harder than many candidates expect is the tone. Multiple candidates described the conversation as probing and even quiz-like, with interviewers pressing on what was missed rather than helping them build an answer. For an entry-level role, that can feel unusually unforgiving, and it suggests AECOM may value candidates who can stay composed when challenged and defend their reasoning under pressure. We’ve also seen that the experience can feel more draining when communication is slow and feedback is sparse.
The non-obvious signal here is that AECOM seems to reward people who can connect technical sustainability concepts to the broader project context. Candidates who only memorize definitions may struggle when asked what a development needs or what the downside of biomass is. The strongest impression we get is that they are testing whether you can think like someone who will advise on complex infrastructure decisions, not just someone who can recite them.

The interview process was much longer and more draining than I expected for a graduate business analyst-type role, and the communication was poor throughout. It stretched over about six months and ended up being three interviews in total, with the final stage lasting around an hour and a half. I never really felt at ease in the interviews, because the style was very much about testing me with trick questions rather than trying to understand how I think or what my approach would be on the job. After I answered, the interviewer would sometimes say I had covered a few points but missed others, which felt harsh for an entry-level role where I’m not expected to know everything already.
The questions themselves were mostly around sustainability and development concepts, which made sense for the role, but the way they were framed felt a bit like a quiz. I was asked things like what matters more between embodied carbon and the circular economy, what is needed for a development, what the problem with biomass is, and what I would include when creating a sustainable community. The final round was especially intense, and the delays between stages made the whole thing feel even more frustrating. I also noticed that only men interviewed me at the final stage, which added to the uncomfortable feeling. In the end I didn’t get an offer, and the process honestly made me question whether I’d want to work there. My main takeaway is to be ready for sustainability-focused questions, but also to expect a very probing interview style and slow communication.
Prep tip from this candidate
Be ready to defend tradeoffs between embodied carbon and circular economy, and to talk through practical sustainability choices for a development or community design. The final round seemed to lean on probing follow-up questions, so practice answering clearly and calmly without assuming the interviewer will guide you much.

Synthesized from candidate reports. Individual experiences may vary.
The process began with a first interview focused on sustainability and development fundamentals relevant to the business analyst role. The interviewer asked probing, quiz-like questions to test knowledge and reasoning, such as embodied carbon vs. the circular economy, what is needed for a development, and issues with biomass.
A second interview followed after a delay, continuing the same style of sustainability-focused questioning. This stage appeared to dig deeper into how the candidate thinks about sustainable communities and development concepts, with the interviewer challenging answers and pointing out missing points.
The final stage was the most intense and lasted around an hour and a half. It was still centered on sustainability and development topics, but with a more rigorous, high-pressure format and slow communication between stages before the final decision.
