Whether prospects of getting employment increases?

I am LLB and has enrolled for PGD In taxation at Indian Law Institute. The curriculum of taxation at LL.B was not vast .Moreover, It was based on case study approach. I wanna to know whether PGD in Taxation will going to be helpful in better placement

Kindly suggest law firms in New .Delhi/South Delhi which provides employment to the Advocates specialising in Taxation
