I applied in-person. The process took 2 months. I interviewed at Siemens (Johannesburg) in Aug 2014
Interview
The interview was difficult with 3 managers present, including the Division Head. They all wore "Poker' masks and were difficult to read and interpret.
When about to answer a question they would ask something off-topic trying to throw you off balance and to see how well you handle the extra pressure and if you can think on your feet.
