Northern Ireland Civil Service interview questions

Passed the online tests and had an online interview scheduled 4 weeks in advance. Got a phone call on the morning of the interview to cancel. They provided less than 24 hours notice for the reschedule (which didn't suit) and would not accommodate any other days or times.

I was rejected, however the feedback provided did not make sense as I met the eligibility criteria, yet they said I didn’t. I asked for clarification and a second look, but they bluntly replied stating that they stand by their decision.
