Difficult to schedule interview due to panel in states. Got many weeks (and many hours preparing) into the process before rejection due to lack of essential experience that I never said I had. Took me way too far through the process for someone who didn't have an essential item on their CV. Waited many weeks to hear outcome. Got into the interview that I'd prepared many hours for, and the manager said 'oh yeah the job has changed and i need to update the jd'
