I know someone who attended Jaipur Institute of Management, here is his review. 

Features of Institute:

• The faculty of the institute is helping and supporting the students in any way. They have vast knowledge about their specialization subjects. But the management is not perfect.
• The management of the institute is not that great.
• The infrastructure of the institute is decent. It has a Wi-Fi facility, fully-equipped conference halls or classrooms, auditorium, indoor and outdoor sports facilities, separate furnished hostels for men and women, etc.
• The administration is trying to improve the placement. In recent years, there has been an upward trend in the placement record. 

The crowd at the Lucknow campus is better than the Noida campus because the students are trained to get better placements. But the Noida campus places more focus on concepts.

Overall, the institute has been growing over the years and has proved to have high potentials. Although, it is not yet amongst the best B-Schools in India.
