I was happy to get a first round interview as I had relevant experience but had been rejected for a few other positions. The first interview went well with the recruiter who asked me typical screening questions. I was then given a second interview a few days later. However, 24hours prior to the interview, it was cancelled with no explanation other than "they were going in a different direction". I asked if they could elaborate e.g. Did they fill the position? I got no response. I can take disappointment on the chin but it's frustrating when they offer no explanation, especially for a company and role you know well and had prepared for.
