What to do?

Hii all,

i have joined my articleship in oct in a small firm in delhi after clearing gr 1of ipcc in may 2012 due to lack of source. now i have also cleared 2nd gr in feb. but even after giving resumes in all the major firms i get no reply from them.ca articleship is the golden period of student life... but here i felt most of the time remain vecant and idle. i want to work in a big firm with full dedication but...

please suggest
