Sayyed, IIM Raipur

No, it doesn't. In India, most institutes do not specify work experience as an eligibility for PGP. But, most of the institutes give weight to work ex for interview calls and admission procedure including IIMs. In IIM Raipur, almost 40% of 2016 - 18 batch do not have work experience.

No it's not at all the case that institutes offering MBA course admit only the candidates with work experience. In fact the trend is such that, all the top institutes like IIMs, etc want to ensure a balance between the number of freshers and work experience students. However,  the proportion of Fresher and work experience students admitted might differ in different institutes in different years depending upon a number of factors which are beyond the scope of current discussion. If you are a Fresher, you will be solely evaluated on the basis of your CAT percentile, 10th & 12th percentages (certain institutes give very little weight to these percentages too),  your graduation percentage, other academic and non-academic performance during your under graduation, WAT or GD and PI, ultimately. On an ending note, let me tell you that IIMA in one batch had 65% freshers and the trend remains pretty much the same. Almost every IIM today, tries to ensure at least 30% Fresher students in its batch. 

Nevertheless, if you are giving CAT'18 then wish you all the best!!
