In my experience I have found that unis all want someting different, I was told by Glamorgan that I had too much information about myself and not enough about the role of the midwife, I had an interview at Swansea but was unsuccessful due to a lack of 'sensitivity' (hand written and UNDERLINED after the tick boxes, must've really upset them!lol!) but had interview and conditional offer for Cardiff??!! Really I think it pretty much goes on whether they like the sound/look of you on the day. But definately go with what feels right for you otherwise I think you sound a bit false and a bit contrived. Sorry to go on a bit but the whole thing baffles me!
