Creditsafe Knowledge Manager interview questions

A 30 minute chat with 2 hiring managers was arranged. A day before this, I got an email from the Talent Acquisition saying the position had been closed. I checked and found this was sent in error. I then attended the interview and was not asked once about my CV. I then received a rejection email less than 50 minutes after the interview ended despite one of the interviewers saying if I had any questions or queries, to get in touch with you over the 'coming days' and I would likely hear from them on Monday/Tuesday. This now feels incredibly disingenuous.
