For reference, the comparison to Asians in the US job market seems misplaced.
From the numbers I found, the representation of Asians in admissions, industry and faculty seems to line up pretty accurately. They represent 10-11% of STEM students, 13% of STEM workers, and 11% of STEM professors. I didn't find detailed numbers for IT specifically.
On the other hand, according to what was written in this thread, OBC people represent 50% of IIT students, but only 1/180 or about 0.6% of IIT professors.
