if they no longer consider you, they will send your an e-mail. I got rejected by my 2nd and 3rd choice, and doing the second round interview with my 1st choice later today. So if you haven't gotten anything yet, I'd say they're still reviewing your qualification so don't give up hopes on it yet! I waited 3 weeks after my first screening and I thought I was out too, but then I got an e-mail a few days later
Good luck and check back on this forum! Candidates are updating their recruitment process almost daily so its really helpful to see where you are in the process in comparison to everyone else's!
