100% placements do not happen at BBA colleges, including the top ones, for many students go straight to graduate school after earning their bachelor’s degree.
That said, the following schools have good placement cells:
1. Symbiosis Centre for Management Studies, Pune (Fair disclosure: I am an alumnus)
2. Anil Surendra Modi School of Commerce, Narsee Monjee Institute of Managment Studies, Mumbai
3. Symbiosis Centre of Management Studies, Noida
4. Symbiosis Institute for Computer Science and Research (offers a BBA in Information Technology)
5. Shaheed Sukhdev CBS, University of Delhi
6. Symbiosis Law School (offers a BBA+LLB)
7. IIM Indore (Not a BBA per se, but the institute runs an 5-year Integrated Program in Management, which leads to a PGDM. Highly recommended)
8. Christ University, Bengaluru.
