IIM Calcutta interview panels typically have 3 panelists (mix of professors and alumni), each panel interviews 7-8 candidates in a morning or afternoon slot, and each interview lasts roughly 20-30 minutes depending on candidate flow and how early in the slot you are. The OP in this thread was interviewed for about 27 minutes in the afternoon slot at IIM C Joka campus by 3 male panelists (2 in 50s, 1 in 40s), with one non-professor (alumni or industry). Being candidate number 2 in a morning slot can mean a 40-minute interview because panel energy is high; later afternoon slots often compress to 15-20 minutes due to panel fatigue.
The panel composition matters: finance-background panelists ask finance questions, HR-background ask behavioral, sustainability profs ask ESG questions. You can't predict panel background, so prepare across domains. IIM C charges Rs 27L fees and places at Rs 34.
