The interview itself was very pleasant - they were very chatty and generally warm and welcoming, it's the behaviour after the interview that was the problem. They promised they would follow up via phone whatever the outcome within a couple of days - unfortunately this didn't happen. I followed up by email twice (1.5 and 2.5 weeks after interview) to be ignored. They then relisted job everywhere without following up - which is incredibly rude and unprofessional.
