Hey
Serdarh, you still have a good chance. No news means good news
As long as you don't received an email (rejection normally via emails), a call should be coming your way. I think your friend who got her result so early is purely lucky because most of us have to wait for more than 4 weeks or more to get our golden call. So don't give up your hopes just yet. Being patient with the recruiters is the way to go
Good luck and wish you all the best~
