Well if you go to maersk site you will get a lot of useful tips on what the interview is like.It is a global company with a lot of oppurtunity.
I will like you to let me know if you wrote their text in july, and is this interview you are been invited to, the second stage?
I wrote their test in july and I got a mail informing me that I may be invited for another assessment.I have not heard anything from them since july.
