There were three rounds of interviews, which were generally exactly the same format. Each interview is split into general competency questions followed by a case-study. The person interviewing becomes more senior with each round. In the end, I passed all of the interviews but I wasn't given an offer as they weren't able to take someone with my profile since I'd need time to get accustomed to the role. I was looking to hop disciplines, so would need to have been trained to do the role they were hiring for. However, they did encourage me to apply for another position. Overall, the interviews were fairly straightforward and the interviewers themselves were friendly. However, Aurora's processes are strange and disorganised. For instance, I was invited to interview with less than one days notice, and they'd take weeks to follow-up after each round despite saying they'd be in touch within a few days. After my final round, it took them almost two months to come back with a decision (instead of one week as promised). Also, during the interviews I asked each interview to reflect on their time at Aurora and their development, and frankly speaking none of them seemed particularly enthusiastic to be working there. It really wasn't an inspiring process. My advice for prospective applicants: • Know the role you're applying for and your motivations well. You will be asked about this at every stage. • Read up on recent energy sector developments as you may also be asked about this. • The case-studies are not particularly difficult so do not worry about preparing too much. Generally, I'd recommend getting comfortable with units and conversions. For example, know how to convert between: kWh and TWh; kW to kWh; £/day to £/annum etc. • I had an Excel sheet open during my case-studies and used it to do my calculations. The interviewers did not mind this and in fact seemed to be impressed by it at one stage. • Try and talk through your calculations as much as possible, otherwise there's quite a lot of awkward silences.
