Indira Pune is not the best choice for an MCA degree. So I wouldn’t comment about it in my answer.
MIT Pune offers good academics, and VIT Pune is known for its placements and ranking. MIT offers an MCA in Management, whereas VIT offers an MCA in Engineering. MCA in management includes subjects such as Business, Finance, Cost Accounting, etc. MCA in engineering revolves around engineering subjects.
If you have an interest in this degree, join VIT. But if you are simply seeking a job in the Banking/Finance sector, choose MIT.
I would personally recommend you join VIT Pune. It is an autonomous college and its syllabus is regularly updated. But you must make a choice based on your preference.
