One of my close friends was an MBA alumnus at IMT Ghaziabad and here’s what he had to say.

Yes, you have to quit the job if you want the course regularly.

However, for an executive MBA course, you do not have to quit your job. All you have to do is just find a study center nearby and apply for it. For the executive MBA course, you can attend the classes during the weekends. Also, make sure that you are available during the examination times.

And for the regular MBA course, you have to clear the CAT examination. You can find the admission criteria on the official website of IMT Ghaziabad. The selection process is similar to IIMs.
