It's all about your marks. My friend with no extra-curricular and no work experience got a position in actuary for PwC and consulting for Deloitte in the asme summer.. she is not even final year... only 2nd year out of a 5 year degree.
Another friend got PwC economics ... which is pretty tough b/c there was only 1 position and a National Scholar at UniMelb (which pretty much means he was top 10 in VCE/HSC) who is apparently top of Eng/Law for 4th year was fighting for it. Again... my friend was only 2nd yr of 5 yr degree.
They tell you they want well-roudned people... but the moment someone slighty on the straight HD/H1 side pops out.. they don't care about any extracurricular.
But guess what.. they both including myself got rejected by KPMG b/c we weren't penultimate year. Only KPMG and EY are so strict with this penultimate year thing.
