I will tell you about a General Category Male candidate (The most screwed guy for JoSAA)
JEE Mains Rank is 10887 (185 marks after revaluation of answer key). Below expectation result in Advanced, so can't get IIT (10782). Didn't had Interest in any branch but by placements, I could understand why everyone preferred CSE. But CSE, I could not get in any top NIT (Not in my own city), my father is a contractor and told me about civil engineering and it's long term gains (which we cannot forsee just by looking at the placements of UG ), so chose it. (would not have taken mechanical even if I got it in IITB). .
