Hiya!! The above 2 posts are right! I applied for Eurofleet not long ago and it was the same!! I was really nervous but I still got the job!!
All I would say is be yourself, be friendly, smile at everyone, chat to the people in your group etc. Like someone said, they do look at the whole picture and the whole process is very professional the way they do it! Prepare some work based scenarios you have been through for the interview ie. when you have given excellent service, worked in a team etc as they do ask lots of questions about all this. But dont be scared because as long as you prepare some scenarios you will be fine! Do take part in the group discussion but don't dominate or take over, listen to others and respect their opinions! Oh, and there are NO tests!!
But don't be nervous for the day, they are friendly, it is professional and they do look at the whole picture of the day, you will be fine!
