Omar its the wrong place to ask for an answer to your question as the previous reply to your question testifies. Watch this thread disintegrate into an anthology of posts riddled with snobbery and vicious putdowns. So much for chivalry eh lads?
That said, as long as you meet the initial requirements then its up to them to select who they think is right for the job. All you can do is be yourself on the day. If you have the time, do an interview prep to polish up any rough edges that you might have in the way of conveying your answers to the psych and the panel. Good luck.
