I experienced an EDF hiring day format that felt friendly and well-paced, with multiple activities and feedback soon after.

  • Workshop / assessment day (online, full day) — I joined an all-day Teams workshop with about 20 other candidates; the team kept things human with multiple breaks and I received feedback quickly afterward by phone.
  • Assessment centre (full day near site) — I went through an introduction to EDF and the current graduate cohort, then participated in team exercises, a pre-selected-topic presentation, technical discussions, and rounds of strength/experience and interaction with the grads. Outcome: No offer, and the main takeaway was that the day format emphasized collaboration and performance under interview-day conditions.
