Going off-topic and I'm not aware of your circumstances. And it might sound a bit idealistic and grandiose. But please don't let this world nibble away your self bit by bit. You do whatever you wish. Also Statistically speaking one is hardly a good sample space to draw any conclusion. For that matter, even 5 is less. It goes awful, let it go awful. Big deal!! Every one has their share of bad interviews. In School, 8th grade my teacher made me deliver a speech in front of the WHOLE school. I was scared to death in the run up to the speech and during speech stammered a LOT!! Post ceremony I devastated. But you know what my teacher did ? She once again assigned me the speech in the next ceremony!! Thank you Shelly Ma'am.
