How was your interview experience at IIIT Delhi for an M.Tech in Computer Science?

This is how my interview at IIIT Delhi for M.Tech CSE went-

At first, we took an MCQ based aptitude test. The allotted time was divided section-wise. After that, around 160 people were shortlisted for an interview, and 6-8 panels were formed. Every panel asked a different set of questions. 

I was asked about my background, and the reason for doing an M.Tech. Then the professor asked me for the subjects I was confident in. I chose DS and Algorithms. I had to come up with a suitable data structure for a situation. I had to also write a code for the same. The professor kept on modifying the constraints, and I modified the solutions accordingly.

 It was an intense discussion. At the end, I was asked if I had any questions. Finally, he told me to go. Some panels asked questions on OS, DBMS, CN. Some candidates were even asked questions based on their current job. 

Though I wasn’t selected, the interview experience was quite good for me.
