In germany apart from Lufthansa only the Lufthansa Regional partners require their applicants to have passed the "Grunduntersuchung (GU)", which is the first stage in the Lufthansa selection program. If you want to work for Lufthansa or one of the directly associated airlines (LCAG, CLH, GWI), you have to pass besides a simulator evaluation the second stage at the DLR as well ("Firmenuntersuchung (FU)"). If you fail at any stage you cannot apply for Lufthansa again. If you pass the first stage but fail later, you can still apply for the Regional Partners excluding CLH, which are: Augsburg Airways, Contact Air and Eurowings. These airlines have their own programs for the simulator and the psychological evaluation.
Apart from LH or LHR, no one in germany gives a s*** whether you passed the DLR Test or not...
