I have completed my BA.LL.B and I am now confused as to what should I pursue now? LL.M in Corporate Law or Diploma in Company Law or should i just work for a small firm and add more value to my CV or get a diploma or a masters degree in Intellectual property law. Which one would be more beneficial for my career and more economically rewarding for me?

And how can i get into big law firms like AZB,Amarchand&Mangladas etc etc.
