Which is better after completing my MBA? Starting my own venture or first take experience and then starting?

There is no straight answer to this. I suggest you to opt for a job for at least 3 years if you do not have any prior experience. Doing a job gives you experience in managing people, finance, budgeting, marketing and day to day affair of a job. You should either join as executive assistant in a star

I would like to invite @||Govind_S|| to share his experience.
