MBA Finance

Hi Manisha,
There is no particular choice here, but since MBA applications or admissions prefer candidates with high leadership and managerial skills you should ideally look for a job that would require you to display these skills. If you want to do MBA finance then gain some work experience in the finance sector.

This would depend a lot on your interest areas and career aspirations.
Depending upon your skills and interest areas you could seek employment in any of the following areas:
1. Accounts & finance
2. Treasury
3. Equity market
4. Broking
5. Investment Banking
6. Banking
7. NBFC
8. Insurance
9. Microfinance

You should follow what your heart is saying, as you have handsome amount of work experience in a promising sector.
If I were in your place, I would take finance.

There is no any hard and fast rule that you must have to gain work experience in finance in order to get advantage, however it is always very much beneficial too.
Banking sector
Insurance sector
Stock and share market
Accountant post etc. will be very good thing to add up in your CV.

I respect your question, but at this time you need focus on your B.Com, because you have 3-years for thinking about it and you have to gain knowledge about accounts and how big companies manage their financial situation problems etc. So, if you want to know about this, read out the articles of company and enhance your knowledge. All the best.

Hello,
I believe by CS you mean Computer Science, B.Tech CS has absolutely no correlation with MBA Finance, in which case it will be an entirely new ball game altogether. Though you are eligible to apply and can pursue if you clear the entrance process successfully, finance is an entirely different specialised branch which opens up fields like investment banking, financial and accounting profiles, financial analyst, etc.
Why do you wish to take this diversion in career?

MBA in finance is good because it has many career options. But if you want a good college then don't keep only MAT as option, you can try other entrances like CMAT and others.
