      Application

      I interviewed at Dwr Cymru Welsh Water (Cardiff, Wales) in Sept 2025

      Assessment centre, group activity followed by speed interview round, competency questions revolving around resilience, empathy and communication. They were nice and it was overall a good experience. The group activity was about seeing how you think things through.
