I applied online. The process took 3+ months. I interviewed at AT&T (Bratislava) in Sep 2013
Interview
The Hiring and the Interview contains from 3 parts: first the Logic Test, then who got enough points from the test could go to the 2nd part, where is the Role-Play Game (which is really fun), and after this part there is the 3rd - the real interview
Interview questions [1]
