I applied online. The process took 2 weeks. I interviewed at MAERSK (Copenhagen, Capital Region) in Oct 2014
Interview
IQ and personality tests. After shortlisting, a personal interview with 2 managers.
The IQ test is made so that 10% of Danish citizens will pass, so beware its not a piece of cake.
Personal interview quite tough, but not the most difficult one I have faced.
Actual hiring process and contract can be a bit long. Be patient, its a good company.
