I have done my engineering with 59% and I have 5.5 years of experience. Which exams should I prepare for in order to pursue executive MBA?

For an Executive MBA programme, you need not appear for an open test. Most of the top MBA colleges also run their Executive MBA programme ranging from 12 to 18 months. Try for an institute that is near your place as many institutes also offer the facility of on-campus attendance of 4-8 weeks or week

Hello sir, 5.5 years is really a huge time period to gain work experience. If you want do MBA then I will suggest you to go for CAT and GMAT through which you will be able to study in the top IIMs and even foreign institutes.
