This was for an internship at Morgan Stanley. I had got through to the interview round after clearing the first round written test. It was a coding interview(which I seemed to have forgotten and will be evident shortly.)

The very first question( which I should have been more prepared for) was 'Tell me about yourself' . Again let me remind you it was a coding interview and the dumbass that I am , ended this answer with "and I am not as good a coder as I would want to be", in reply to which the interviewer said ''Let us not underestimate ourselves.'' . This is where I should have kept quiet and waited for the next questions or maybe agreed with the interviewer. But this was not to be and I immediately replied back with 'We must also face reality'.
*Awkward silence* followed by a "Hmmm" by the interviewer made it very clear the direction is which the interview was to proceed.
It was as if I didn't want the internship (Let me assure i did want it).

However, lessons have been learnt.
1) Be prepared for the usual expected questions.
2) Speak the appropriate amount . No less and more importantly no more.
3) Don't act over smart.
4) Sleep well before the interview.
