The HR was so arrogant.
The were so unfair that they gave half an hour to each student in the beginning talking about projects and than at the end, the left students were given only 2-3 minute due to short of time and just asking technical questions judging them in one question.It is your problem that you have less time.Why you are being so unfair.There should be fair chance for everyone.
Hiring team just do a formality to show it to their seniors that they went to hire.They will just select the ones who came in the beginning no matter how good others might be.
Give equal time to everyone.
If your are not capable of doing it , don't do a formailty..
