What is the reputation of arts/humanities courses of IIT Madras?

Some of my close friends go to IIT Madras and according to them, the admission process of the Humanities courses is quite biased towards the native students.

In the past, there have been instances where the list of selected candidates contained only those belonging to the South-Indian states. Also, they don't show the marks and it's only the final merit list with the names of the students. Although there is a huge number of North Indian candidates who apply for the admissions, unfortunately, they didn't get one. The admission procedure in itself is not very transparent.

The placement record for Arts and humanities branches is average at best. There are not even non-technical jobs for the arts and humanities stream.
