Articleship in big 4

Better to approach them through references, if any. I guess some cci students are working in Big4's. Send them through their references. Also a well prepared resume plays a vital role in shortlisting the resumes. All Big4's dont have email ids to apply. For now, PwC is accepting online applications, so you can apply in below link if not done earlier. Hope this helps.
