I have been interviewed in STN in July 2011. Then I have received the email saying that I didn't pass...after a few months I have re-applied with two more email addresses and I've been called again in April 2013; obviously, you don't wanna mess up with them, so when they phoned and asked me whether or not I had already been called for an interview I said 'yes'. They said they would have let me know and my application got rejected one week after.
