Hi,
You should try for GMAT if you can afford to do
MBA from outside India else you should go for
CAT if you can work so hard and manage to get into IIMs. If neither of the two mentioned above you should try for
MAT that is easier to qualify as compared to others and you would be able to get an entry into good college.
You can also go for distance
MBA in case you do not want to leave your job. It is also fine since you already have work experience but anyhow would carry less value than a regular
MBA. It is not recommended to go for online
MBA since in India still it is not given preference as compared to a regular
MBA.
You should choose IT or marketing or a combination of the two in
MBA to get increase your job prospects.
