You have average chances to get into MDI and XIMB. Though past academic records are not given much importance and therfore with a percentile above 97-98 and good performance in selection rounds like GD/PI/WAT you can get into the desired college.

Keep your profile good and invloved with extracurricular activities and you stand a chance. 

Your work experience will be an add on. So get prepared for the entrance.

Good luck!!
