Interview Jitters...

It's almost one year that I gave my first interview for a job but still today the very call of interview sends shivers down my spine.I am still not clear what the fear actually is all about. Is it about confronting those new sets of intellectual(assumed) people or is it that I don't want others to make me feel that I am not all that good. Still after umpteen number of interviews that feeling of failure rips me apart.
Last week I went for one more interview, hardly prepare for these non existent companies anymore. But still, the jaunt till the comapny gate I could feel butterflies in my tummy. I was well before time. Took a deep long breath and sat on the couch at the entrance with a stupid smile pinned on my face as people say depicts your cheerful nature.Gave a close look to the every detail of the company from bean bag lying on one side to the employees going and coming every now n then. "Not bad, I want to work here, sit on that bean bag..." the first thing that came to my mind, And then like a normal piscian started day dreaming.....
The gaurd uncle( something about him makes me give this respect to him),an elderly person made me feel quite good. He made me genuinely for the first time. After 15 minutes came a young guy, pretty ordinary Bong guy. Both of us had one thing common,both of us had not done out homework properly. He asked me to write some SQL querries even he wasnt sure of. But he had something that made me feel comfortable with him in that anonymous place. Then comes an IITian, a typical one..which gave me some confidence to boast about IIT.
Well that was it.. we chatted for almost 45 mins and I was very confident for thoes 45 mins. They seemed happy to meet me and asked me to wait for the reply. Still waiting though.......
On my way back home I realised that my confidence was more like my attitude to them and I am being stupid to call my arrogance my confidence.
Well people say you learn from this, a small cost to pay for a big experience. But do we learn? I am what I am.. That's me , is being honest or being yourself is what you pay for. And there are lot more similaar questions running over my mind which I am not able to put across my blog.. I think you can put your thinking cap and reply back to me.
