The hiring process I experienced with WU was as follows: after I was selected for an interview, my recruiters told me in advance to have five references ready and to ask them to be "generous" with their feedback (ie solid gold 100% positive feedback). They stressed this fairly heavily. The interview itself lasted about an hour and a half, during which I took a short accounting test which mainly focuses on intercompany accounting, timing differences and basic foreign currency accounting. A few days later I was asked for my references, and a few days after that I was told there was a "problem" with one of my references and the process could no longer move forward. No word if this individual gave me a 0% or just 95% positive feedback.
