MAERSK Incident/Problem Manager interview questions

Long winded and dragged out. Turned up in good time and was left waiting for over 50 minutes past the appointed meeting time. The interview was very cursory and offhand as well as short. Basically they had already appointed and didn't have the common decency to advise and cancel before I hired a car and traveled some distance - investing time, effort and money into a wasted effort. I was offered another interview (telephone) later the same year. When I found out it was the same person, I wasn't optimistic but definitely not surprised when he didnt call! The other candidate pulled out as the interviewer was so unprofessional! Whether this is one person or indicative of the company/department I cant say.
