The interview started well but then the tech didn't work and they could only hear, but not see, me. Added to which, one of the panellists kept disappearing and reappearing online, a bit like a Cheshire cat. However, instead of halting the interview to work out what was going wrong and then rescheduling, they decided to continue regardless, which I thought unprofessional. and inconsiderate, given the amount of preparation time I'd given to this opportunity.
