Hi,
First of all you need to understand why and which MBA you want to do it.
I advise to go for full time executive MBA / PG management programme designed for working executive from top level institute like SP Jain, ISB Hyderabad, XLRI and IIM
If your job does not allow it, then go for part time MBA/ Evening MBA from a very reputed institute, As of now, following institutes offer such programmes:
JBIMS, Mumbai
ADMI, Mumbai
N L Dalmia, Mira Road (Mumbai)
FMS, Delhi
XLRI
ISM Dhanbad
Still, if you do not want a part time also, you should opt it from a good central and state universities only. Never opt MBA from private universities in India.
The good institutes are:
Pondicherry University, DDE
University of Madras, DDE
Anna University
Kurukshetra University
Bharti University
