Leaving a PSU bank for a baby IIM only makes sense if you can convert fresher MBB/IB interests with 3+ years ex and target a specific industry pivot. PSUs pay Rs 18+ LPA entry and have great WLB, so the opportunity cost is real. IIM Rohtak charges Rs 16L fees for a Rs 18 LPA average (essentially no pay bump over PSU), and IIM Ranchi charges Rs 14L fees for Rs 17 LPA.
The ABC AMA was blunt: "Not too familiar, should be 50-60 in 4-5 years" at a baby IIM - meaning the long-run compounding is weaker than PSU + internal promotions. Only switch if you have a clear pivot (consulting, product, startup) that PSU cannot offer. The financial math: Rs 16L fees plus Rs 18L opportunity cost over 2 years equals Rs 34L invested to go from Rs 18 LPA to Rs 18 LPA average - a 4+ year payback at best.
Push for a 97+ percentile and target MDI, IIT B/D, or aim at ABC through a drop year instead. If you're stuck at 93-94 percentile, stay at PSU, pursue CFA, and retake CAT next year. Check your eligibility at collvera.
