MBA is a tool to open doors, it's an expensive networking exercise masquerading as a degree. If you're not doing it full time, live and with actual people who can form relationships, friendships, mentorships with you, an MBA is pretty much useless.
If it's the management education or knowledge you seek, go pick a good reading list of the courses taught and work on them yourself. You don't need to burn a hole in your pocket.
As yourself why you need an MBA. And where you're getting it, would that justify the cost of whole exercise + opportunity cost of not working for duration + any other benefit.
If you want to be PM, become one. You don't need an MBA. A bunch of online reading and building side projects + real world experience should be enough.
If you really want MBA to change your trajectory. This would be the order of value:
- Full time MBA - top 10 institution.
- Executive MBA full time - top 10.
- Part time + live on campus - top 10.
- Full time MBA - no-name institution.
- Executive/part time MBA - no-name.
- Online MBA - video courses + tests.
If you don't get 1,2 or 3, just skip it.
