CA Articleship (Advice from CA Students and Qualified Chartereds)

Hey there, I have just appeared for my CA inter and I want to use this time before my results to research about my CA firms in Vadodara. I will not be able to relocate for from vadodara and thus want to choose a firm in Vadodara.I have heard about a few famous names like KC Mehta and Mukund and Rohit and thus I want to know more about the working culture over there. And please suggest me some more big or mid size firms.Have heard that mostly all the firms have a bit of politics here and there but want to know exactly about that. And can someone also guide me about the requirement of referrals in these big firms, since I don't have any strong referral currently.(which justifies me posting here lol).
