Cs internship

in my view... better you go for industrial training because it will give u a larger scope and it will add as experience in your CV at the time of job.. 

At accounting firm or big 4 you will only do lot of work only nothing else... your knowledge will not increase

Still if u wanna go there inbox me i will forward you an email id of my close friend who can give you chance at PWC after seeing your cv and interview..
