Which should I prefer, Pumba or mitcon for pharma MBA?

You should definitely go ahead with MITCON without giving it too much thought. Placements at MITCON are quite great, with decent salary packages.

It offers a PGDM course, so the syllabus is not outdated and nor restricted. There are quite a few guest lectures organized by extremely qualified professionals that will surely help you in some way or the other.

As far as PUMBA is concerned, it is definitely a brand in itself for a regular MBA but you will have to ask a student that goes there. However, the Pharma and Agriculture PGDM courses at MITCON are much better. You will have good Pharma placements at MITCON. PUMBA on the other hand offers decent placement across various domains.

So, choose according to your convenience.
