A online coding test. Technical and HR interview. The tech interview involved discussion on my projects. some concept of how processor works and then some coding in C. The HR was basically telling the offer details. But they put emphasis on my disability, how well can you type, can you take equal amounts of weight in both your hand, what is your speed in typing etc. The technical interview went really well. But I didn't really liked the HR one. All such questions really put me in a sensitive spot. But later the HR said that he wasnt aware of the PwD category in govt colleges and thus these questions. Though it seemed genuine but their whole attitude and body language during asking these sensitive questions was not good. The technival interviewer was great!
