How do IIM Calcutta waitlist movements work and when do they happen?

IIM Calcutta waitlist movement typically starts soon after the first admission acceptance deadline ends and continues until class begins or few days after. The OP confirmed - "Generally starts soon after the date to pay for first list ends and goes on till start of class or few days after." Waitlist 37 at IIM Bangalore converts "easily" per OP - similar logic applies to IIM C. IIM C waitlist mechanics:

1. First list published in April-May 2026, deadline to pay Rs 2-3L confirmation fee + seat booking,

1. Waitlist movement starts after first list deadline (typically mid-May 2026),

1. Waves of movement happen: Wave 1 (late May), Wave 2 (early June), Wave 3 (mid-June),

1. Final movement: first week of classes (students dropping for better calls they received late),

1. Overall WL movement: typically 50-100 positions moves at IIM C, sometimes more. Specific WL conversion rates (historical):

1. WL positions 1-50: 90%+ conversion rate,

1. WL 50-100: 70-85% conversion rate,

1. WL 100-200: 40-60% conversion rate,

1. WL 200+: 20-40% conversion rate for GEM, higher for reservation categories. For GEM candidates at WL 100+, conversion happens typically when BLACKI/FMS/MDI admits cascade through. If you are WL at IIM C:

1. Accept the admission conditionally to hold seat,

1. Continue applying to other IIMs and top colleges as backup,

1. Monitor your IIM C portal daily,

1. Don't pay multiple confirmation fees - withdraw from lower-tier calls once IIM C converts,

1. Notice period negotiations: discuss possibility with current employer to hold 2 weeks after WL conversion date. OP noted regarding someone with notice period issue - "In a pickle in regards to notice period at work, and any help will be greatly appreciated" - sadly no fix beyond flexibility from employer. For CA candidates with 98.5%ile at IIM C WL, conversion is possible but tight - CFA charter + CA trumps it further. 99.4-99.6 CA WL candidates have historically failed to convert IIM C per commenter - IIM C requires 99.7+ CAT percentile for CA candidates now.
