I read many career advices,but some problem confuse me.I hope someone could help me. Thanks in advance. 1)I am Chinese,many friends around me believe that get MFE in US degree will help them to go into Wall Street.Is it right?How many people around you have MFE degree? 2)Most of the discussion focus on C++,statistics and machine learning ,few talk about PDE,SDE and functional analysis ,is it useless in Wall Street for quant? 3)In some famous company such as Google and MS, they have a strong research group,and often write,publish paper in journal as graduates do,how about in Wall Street,how many people around you write and publish papers in journal?
