Terryble... If it's only been 3 to 4 weeks since you went for your medical, I'd give it a bit more time. It took them about 4 weeks to get back to me with the contract. To my knowledge, if you're not selected, they let you know pretty quick as evidenced by other experiences posted on this forum. Just be patient man and meanwhile, keep the passion boiling by immersing yourself in more aviation info. Good luck!
