The sole factor which matters in order to get into XLRI to calculate your final score is a certain criterion i.e. work experience. Although this will change year after year and you cannot entirely rely on this. But it is advised to have some prior work experience.
You need not worry about your work experience. There would be freshers along with candidates having 3 to 4 years (or more) of work experience. Various other factors like PI performance, exam score and GD performance would also matter a lot.
All of these are taken into consideration for you to get into XLRI. And as mentioned, just try to carry work experiences for yourself so that your journey gets easier.
