What are the disadvantages of studying in AIIMS Delhi, if any?

A few advantages my friend who was a PG student at AIIMS experienced are 

• Minimum exposure to common diseases: AIIMS has very few common cases as it tries not to admit patients with common illnesses and focuses more on rare diseases. This causes very less exposure to common illnesses to PG students of AIIMS.
• Less Free Hand: AIIMS is an SR-based hospital with super specialization in each branch. This leads to relatively less free hand.
• Work pressure: The working environment of AIIMS Delhi is very tiresome and challenging. 
• Thesis: Students of AIIMS have to publish a genuine thesis as AIIMS focuses largely on research work. This can sometimes be very challenging.
• Medical Representative culture:  AIIMS does not have the MR culture where you are treated as a royal and even are allowed to party weekly. AIIMS is very demanding and a North Indian MBBS student might feel disappointed here.

These disadvantages are based on personal opinions and are not specific to the institute. So it’s better to investigate before joining.
