Behavioral Case Presentation
I had a panel interview with 4 VPs. They asked a lot about National Grid’s core pillars and wanted me to give examples of relevant situations from my job. A case study was shown on screen, and I had to read it and then talk about my approach. They also read a case study out loud and I had to respond immediately. The vibe was super friendly but the questions were intense. I got a rejection letter a few weeks later and no one responded when I asked for feedback, which was frustrating.

I applied online back in June and HR reached out in July to set up an interview. The interview itself was in mid-July and it was one panel round with the hiring manager and some engineers. We mostly talked about my background, my technical experience, and project work, and also some behavioral stuff. It felt pretty professional and conversational, not too stiff. I heard back about the offer in mid-August. The background check stuff, like the drug test, wrapped up in early September, and I started in October. So yeah, it took about four months from applying to starting.

It was a really strange interview experience. The recruitment team emailed me saying I was a strong candidate and encouraged me to apply. After passing the initial Teams interview, I waited three weeks for an assessment day invite. This is for a trainee supervisor role, and I already have over 4 years of experience as a qualified contract supervisor on network build projects. My colleague and I, both experienced supervisors, were interviewed on the same day and participated in a contractor conversation assessment. We both received positive feedback on the day, with one assessor even saying my colleague's conversation was 'the best he'd seen.' We felt confident given our experience and the feedback. However, neither of us were offered a place, and the feedback was very generic, without specific reasons why we didn't meet the requirements. I suspect the training program spots were already filled by preferred candidates, not necessarily the most suitable for the actual job. It felt like a waste of time.

This interview process was really unprofessional and didn't respect my time as a grad. After passing the first screening and online test, I did a recorded interview in November. Then, in early December, they asked if I could be available on a specific date in January if I got shortlisted. I confirmed my availability and kept the day free. This went on for 7 weeks with no updates until the day before the interview when I was told I wasn't selected. They really didn't seem to care about their potential employees' time or lives.
