HI Aspirant,

Its difficult to find colleges with full 100% placements but colleges at around 85-90 percent placement in India are mentioned below:

• PSG COLLEGE
• PSGR College Coimbatore
• Chandigarh University
• Ethiraj college
• Womens Christian College
• Loyola College

These are some good college with good placements rates and awesome faculty and infrastructure.

Hope it helps!!
