1st interview in person with two HOD in office, went well and asked me for a second interview within the hour. Second supposedly more informal interview at cafe/restaurant next door with HOD and deputy CEO. Had researched about the water industry but put on the spot with unrelated technical questions about A-level economic theory. Then took two weeks to reply with email about outcome. When asked for feedback, HR then coincidently went on holiday for 2 weeks. Never responded to my email about feedback.
