You dont have to approach any company for Internship But what you would be doing is Articleship,

Contact some good mediocare CA firm thru some contacts of your Friends / Relatives or parents & Once you approach such CA he will tell you & do the necessary formalities of Signing the articles with Him, Else you can also approach the your Nearest ICAI office & you will get all necessary details & assistance. Welcome to the CA Faternity & All the best for a bright future & success
