I was in the exact position but the HR just wasn't having it. I personally think the sim went ok, if anything its the exam results that got me but i have since reapplied after being encouraged to do so by current employees. I keep updating my CV etc (for kicks) but I've heard nothing from them for over 2 years. If anyone remembers they sent an email out saying to re register and that they do occasionally consider reapplicants but in not sure how true that is.
