With regard to the landing order question a few posts back;
I got asked the same question in my interview when I went through, started with C172/737/747 in that order. It definitely wasn't posed as a question that had a 'right' answer, more testing your reasoning and thought processes behind decisions, and how you reacted to new information or a change in the scenario. I can't quite remember what was brought into the picture to change it around though.
They are looking for the scope to learn a lot of information and then apply it quickly when the situation demands it. In truth, this scenario doesn't really have a 'right' answer as cases can be made for most orders, as long as the order is safe in terms of separation.
