How good are the placement opportunities after completion of PGDM?

Hello! It entirely depends upon your skill sets, the reputation of your college, and the efficiency of its placement cell. More reputed the college, more are the chances of getting better job opportunities.

It depends on the college. If the college has a good placement cell, you will have a good chance of bagging a good job. If not, you do not need to panic. Management professionals are highly in demand these days. You will eventually end up with a decent job anyhow.
