Why GCCs choose Kolkata Salt Lake Sector 5 and Techno Park
The case for Kolkata Salt Lake Sector 5 and Techno Park
Kolkata offers Eastern India's largest and most experienced IT talent pool at 35 to 45 percent lower cost than Bangalore, with one of India's lowest attrition rates (12 to 15 percent versus Bangalore's 20 to 25 percent). IIT Kharagpur's (ranked India's #3 IIT) proximity (100 km) provides premier AI, ML and engineering talent. West Bengal's IT Policy 2020 offers competitive incentives, and Kolkata's BFSI and PSU adjacency creates specific operations and compliance talent depth.
Watch outs
- Kolkata has a historical reputation for political trade union activity; newer companies report lower impact than 1990s stereotype
- Premium AI and product engineering talent is thinner than Bangalore or Hyderabad

FAQ
Common questions about Kolkata Salt Lake Sector 5 and Techno Park
Why does Kolkata have such low IT talent attrition compared to Bangalore?
Kolkata professionals have a strong cultural preference for remaining in their home city, unlike Bangalore's migrant-heavy workforce. The city offers relatively affordable housing, family rootedness and lower cost of living. This creates an attrition profile of 12 to 15 percent versus Bangalore's 20 to 25 percent. For GCCs with high knowledge-transfer costs (legacy modernisation, compliance operations), this stability differential is a material operational advantage.
