If you have an MBA call from BLACKI (Banglore, Lucknow, Ahmedabad, Calcutta, Kozhikode, Indore), XLRI Jamshedpur, FMS, and other premium institutes then you can definitely go for MBA otherwise I would suggest you gain some industry experience for at least 2 years and along with that you can constantly appear for CAT/XAT exams.
It would become easy for you to get admission to a premium institute with work experience, and work ex. will also help you in securing a good placement in your MBA college.
