I want job but no vacancy every place

Hello !!!

I completed my articleship and wrote IPCC May 2013 exams and looking for a good audit firm in Chennai. I called up many good firms but all of them say NO VACANCY !! 

Please tell me what should I do ? I dont want to compromise on quality of audit firm as my articleship was no much productive enough. How to get into a good Audit Firm.

Please let me know if there are any vacancies in good audit firms. If anyone working / worked in such firm then let me know how it is and the work environment in that firm.

Regards,

JK
