If you join IMT Ghaziabad after having a work experience of 3.6 years in manufacturing, you might face issues in a summer internship. As IMT is famous for marketing and finance, many companies either prefer candidates in the same field or freshers, so you can get difficulties in getting shortlisted. But if you choose to finance in your second year, your previous work experience will not matter that much, plus you can showcase whatever you have learned in your summers. What I have felt during my MBA is that there is no barrier if you want to achieve anything. You can always work hard and smart to reach your desired goals.
