It is stern sin to maintain the accounts of interest-based dealings. The holy Prophet Muhammad (صلى الله عليه وسلم) cursed those who give and take interest; likewise, he cursed those who record it. Since, you have to read and write interest based accounts in the companies mentioned above; hence you should avoid such types of jobs. It would be better for you if you do your MBA in other stream instead of finance.
