Which one of the two would be a better choice, IIM Raipur or IIM Kashipur?

IIM Delhi would have been a reality if capital cities were the only places that could draw high-caliber placements. Since many of the participants in this thread appear to be unaware of the paradox that geography affects employment opportunities. 

Slow placements and offer retraction have been a source of complaint for many IIMs. In addition, numerous IIMs, including Raipur, according to the papers, have been asked to submit their reports for review by the MHRD due to unsatisfactory data. But Kashipur is not at all a part of these worrying developments. IIM Kashipur was given the all-clear despite not encountering either of the issues.

If you compare the reports, which basically show people don't give a hoot about geography if they have the quality to be obtained, it still has one of the highest numbers of companies visiting the campus. In contrast, IIM Kashipur's numbers have consistently outperformed those of comparable institutions, and one can also see that the roles available are comprehensive and varied.

So, if you want a quality education and a quality job that will be a uniform outcome of quality education, go somewhere that is off-limits to the rest of the world.
