I'm currently applying to a few graduate schemes in the area of consultancy. After speaking to several on the phone, and reading their website information, I was encouraged to apply as I am in the final part of an MBA and have been working in the private & public sector for ten years. It isn't what would considered relevant work experience, which is why I am looking at graduate schemes.However despite the fact they have encouraged me as a mature applicant, soon to complete an MBA, and I have a postgraduate business diploma with Chartered status, I don't have a graduate degree. I completed the first two years of a degree in Australia, but was granted a diploma when I had to quit due to moving to the UK. I then for financial reasons had to work full-time and therefore have been studying part-time ever since as finance has allowed.On the phone they said this wasn't a problem - just list my grades, plus A-Level/GSCE Australian equivalents - which I have done on their online forms. But now two of them have come back saying I must give details of whether my degree was 2:1, 2:2, First etc. I went back to them saying that it was none of those, as I don't have a first degree - just an undergraduate diploma, a postgraduate diploma and soon an MBA, but they sent another email stressing again that they need a mark such as 2:1, 2:2 in order to submit my application into the processing phase, so please provide an estimated equivalent (even though on their website it says please do not convert international qualifications to UK standards).Any suggestions as to next step, or should I give up (something I am disappointed to have to do, but if they really are not going to consider an application unless it has one field filled in that is N/A to me, then I don't want to waste my time or theirs).
