AECOM Electrical Engineer (Building Services) interview questions

Interview was relaxed but long (1hr + 45). My interviewers were very nice so it felt more like an informal discussion. I arrived a bit early, but was led to the interview room straight away and was offered a coffee while I waited for the interviewers. They were both really friendly and put me at ease. They mainly asked questions about my experiences and why I was interested in electrical engineering. They didn't seem to have to stick to a certain set of questions so the conversation flowed naturally. One interviewer left after an hour but the other stayed and we talked more informally about living and working in Cardiff.
