I've just finished my interview today, so I'm currently waiting to hear back from them. I've had an initial online assessment testing my numerical and verbal reasoning, then that was followed up by an invitation to an online assessment centre (final stage), which consisted of 6 stages: Briefing, ID check, Technical Exercise, Interview, Case Study, QnA session. The technical exercise consisted of 4 exam style questions, testing your mathematical skills (solving equations from given data) and your reasoning for fire safety designs (for example, using building schematics to identify which room is most likely at risk of fire, design considerations). You are given time to solve all these questions, and preparation time in order to present your answers during the interview stage. This interview consisted of three stages. They firstly ask about yourself (e.g. strengths, weaknesses, why you would be a good fit) and what you know about the company/ role. They then ask you to elaborate how you answered each technical exercise question, and they are followed up by questions additional questions surrounding the technical exercise topic. Finally they ask you a couple competency questions, such as how you would perform in the work place and also how you can demonstrate overcoming challenges and cooperative skills. The case study consisted of an exercise where you need to make judgement, and present you answer to the interviewers. You are given a piece of text with a bunch of facts. There is no right answer, but they are testing you to see how you would approach a situation with multiple options, and how you justified your options. Overall the interview process went really smoothly. But they organised it at such an awkward time 11:40 - 16:30, so I couldn't have any lunch. I was starving afterwards. But all the interviewers were extremely welcoming, and they really want you to do well. It was such a supportive environment, where I could express my answers clearly. Remember to research the company and about the role. The exercises aren't there to test your knowledge, but how you approach the scenario and justify your reasons clearly. There's not much you can do to prepare for these exercises. Just be yourself and you will do well!
