to give you more perspective, it more depends on the type of the company, you are applying to .....finance and IT or consluting companies will majoring focus on MBA related subjects but sometimes the core compnaies like TVS, Cummins etc get into grad subjects....so if you appearing PI for such companies its better to just brush up the subjects..
Always have an edge over your abilities in a PI you can be asked question about anything so you should look at some of your favorite subjects. in PI you may not be directly asked about all your graduation subjects but there can a choice for you to tell about your favorite subject
