I went for an interview with them once, many years ago. All was going swimmingly, qualifications were above what they wanted and the interview was nearly over and I had been told I was just what they were looking for! Then atmosphere turned very frosty when I was asked about my hobbies and I told them "All country Pursuits". "Do you mean game shooting?" said the inspector interviewing me. "Yes, fishing and hunting too", I said. That was it, they told me I was unsuitable for the position.
I tried the RSPCA too, same result.
