Can someone share their interview experience of MBA from DMS, IIT Delhi?

My friend was an Economics fresher and appeared for an MBA interview at DMS, IIT Delhi. The answer is courtesy of his experience with the panelists.

The entire procedure comprised of WAT, Documents Verification, ECA document verification, and PI

Everything was done systematically and in an organized manner. The WAT was a 30-minute process and she was made to write on Outsourcing. After the ECA, she was escorted to the interview room where she found 2 female panelists. 

They asked for her brief introduction, something that is more than just her name and educational background. On hearing about her passion for writing she asked what kind of writing she was into.

Owing to her interest in hockey, they asked her some related questions like 

• what improvements does the Indian Hockey team need
• Who was her role model from the team and why
• Why she did not pursue a hockey career 
• Did she choose the game because of it being the national game ( which it is not thus being a trick)

Next she was asked about her School life, age, and past academics. She walked if she had any prior working experience. Being an economics student they asked her

• What is elasticity and asked her to draw a graph
• They asked her what would happen if the demand for a water bottle would be increased

Lastly they asked her about her weakness after which she was asked to leave. The overall interview was a good experience mainly because the panelists, one of which was an alumnus, were friendly and lightened the tension.
