Hey!

In India, as well as overseas, both MBA and PGDM courses are regarded as having equal value when it comes to career prospects. However, if you wish to pursue higher education abroad, a PGDM is considered to be a diploma, while a university-affiliated MBA is counted as a degree, giving you a better standing.

Hope this answer helps!
