MAT

Sorry SIBM-B only accepts SNAP score. The MAT score is not accepted

That's fine if you don't have work exp. You can get selected based on your GD,PI and write up performance and your MAT score is also good. Yes, you have the prob. of getting selected because admission result will be based on your performance here at BIMTECH, your graduation marks, co-curriculum activities, achievements.
So, go ahead and appear for this.

You need to appear for one of the three exams we accept - CAT (Cutoff - 85 percentile), XAT (Cutoff - 85 percentile) and GMAT (Cutoff -650). For more info refer our website www.spjimr.org

No, only the CAT score is applicable.

Yes you are 400 score is required

Surely you will get admission you need to crack gd/pi round

More than 575 for registeration (but it is subject to change as per college authorities

70%tile in MAT.

Convert the marks into percentile. IF it comes up to 70%tile or higher then you are eligible. As for the work ex, yes it will help not only in getting selected to XIME but also placements. Work ex is always prefered by companies. But it doesn't necessarily mean you will get a higher package as it depends on which company you apply and how you perform on the day of the interview. But general trend is that work ex people get higher pay than freshers.

Yes, you are eligible for admissions. Cutoff is 70%tile so you are well above it. Good luck!
