Just planning ahead for my DS who is in year 12 and starting to think about degree choice. He thinks he'll probably want to train in audit for a Big 4 firm after university but isn't sure about degree choice.
I am a CA myself and the advice always used to be that you shouldn't do an accountancy/business/finance type degree because firms often prefer a 'pure' subject (STEM in particular) for the transferable skills. However, through my job I've come across quite a few cv's recently for newly qualified CA's who trained with a Big 4 firm after doing a finance-related degree so maybe my knowledge is out of date?
I'd be interested in your criteria and preferences if you are involved in recruitment...
