I applied online. The process took 2 months. I interviewed at MAERSK (Aberdeen, Scotland) in Feb 2012
Interview
Initial two online tests. 50 multiple choice questions in 12 minutes and a personality questionnaire.
Interview day consisted of a 10 minute presentation on my thesis to a three person panel followed by questions relating to presentation and non-related questions. This was then repeated to another three people panel with more technical questions. These presentations were followed by another 50 multiple choice questions in 12 minutes done online.

I applied online. The process took 2 weeks. I interviewed at MAERSK (Almaty) in Apr 2013
Interview
online tests, verbal and math, time limit, you should be flexible and do everything on high speed, but unfortunately they did not give any replies. The tests were difficult, however you can pass based on your background. Good luck!
