hi,
there are loads of employment opportunities for a biotech grad in this case post grad after MBA. I would suggest take fin/mktg/dual as sopecialization. Most of the Pharma co.s (biotech co.s like biocon dont do much of mba selection) generally prefer some who has a bsc/bpharm/biotech background and if they get the right candidate they lap them up. apart from that if you want to change your industry domain, then also you can move into any related or unrelated fields, now a days many top end hospitals/global pharma retail outlets/health consultancies look for mba having a bpharm/biotech background
if you need more info, pm me ur mail id, i will pm you the contact details of few of my close frnds who are pursuing MBA from India and abroad after doing their biotech grads here in india
ciao..
