Do the students who get in from IPM in IIM ROHTAK and those who got in from CAT get to interview in front of the same companies?

There is only one batch as of now who are currently in 2nd year. Considering the situation of COVID-19, students might not receive placements for at least 4 years. You cannot necessarily point out companies and anticipate their preference towards PGPs.

Even if the recruitment takes place, the process will be as follows:

• IPM students only get placed after their MBA, following the PGPs. The same companies will recruit you whether you have entered through CAT or IPM. Only your academic credentials will be taken into consideration.
• You will have average to best placement, given your academic backdrop in both graduation and PGP, as opposed to the students of CAT.
• Students who enter via CAT usually get serious after 2 years of their studies. There are students who indeed pursue their graduation from several institutes that are not highly spoken about and choose to study Engineering or Commerce.
• In contrast, IPM carries a very rounded curriculum vitae, supporting their thoughts to reach beyond accounting or economics and similarly helping them construct an accurate amount of mindset in every individual field.

If you have pursued BBA from IIMR, then you will remain several steps higher than someone who studied in a college not greatly renowned. There are very few chances that an IPM student would be placed lower than PGP. It might be a little less, but this is seldom seen.
