Im so fortunate that we were given a practical for our job interview.Otherwise I just couldnt make the cut,I am you typical geek,extremely shy,I stammer in social situations and I can hear my quacking sound while I speak...but its all good,I have learnt to accept myself and even laugh at me.
Even Kifaki gives hopeless speeches and yet hes prezo,and most of the people I know who've made it are not so eloquent in speech just be yourself.Your day will come.
