HI TangoTango
I believe its more policy that a candidate has to wait a minimum of 6mths between interviews. Don't be too sad, as this time can be translated into a lot of self reflection, improvement and also try to get some renewed sense of belief in yourself.
If you have read my earlier posts, I have gone for first interview 3 times, still not successful..but not givin up as yet.
It doesn't matter if its not meant to be, but as long as they are still keen to give me a shot at the interview, I will try. So don't u feel too disheartened.
Wish u all the best and my only advice to you is, while u continue to harbour your desire for this career, life must go on, don't stall all things for this ... for all you know, you may strike GOLD in other areas and earn so much that you may just earn your wings privately someday and fly solely as a hobby..
Cheers!
