PES (UK) interview questions

I went through a multi stage interview process which involved a telephone interview and 2 face to face interviews. I traveled from Cardiff to Bristol for both of these interviews. I was told I was down to the final two candidates and only reference checking remained. This was the last I heard from the company, no rejection email, no responses to attempts at contact from myself, nothing. Extremely disappointed in PES Consultancy and their recruitment practices especially considering they specialize in HR. I left my previous position on extremely good terms so I also know the references were positive. Very unprofessional.
