I came through a referral from someone already working there, and the process moved pretty quickly. I didn’t go through an assessment centre; instead it went straight into a technical interview with a director and an engineer, and then I had an HR conversation to wrap things up and finalise the job.
The technical part felt like a realistic conversation around the role. I got asked questions across a range of building-services/mechanical engineering topics, including basic design principles, and it also touched on how I think about solutions rather than just facts. On top of that, there were a couple of competency-style questions mixed in, so I had to connect my answers back to my experience.

I experienced the process as something that really hinged on the assessment centre. Before anything else, there was basic screening from the hiring teams, and if I passed that step, the assessment centre became the final stage.
At the assessment centre, I went through two rushed group tasks plus a competency-based interview. Each group task had very tight timing: we had a short window to discuss and then only a few minutes to present what we’d come up with. It was surprisingly pressurised, because there wasn’t much time to find your footing—just enough to organise ideas quickly. There was also guidance around making sure I knew the company well, showed up on time, and treated the preparation seriously.
