Not really FullForward, the scenarios they have are not unreasonable at all, standard OPC material which any experienced pilot shouldn't have a problem with. They put together two people from different airlines, different countries, both not native english and at least one of them not current or experienced on the 737 and expect that you deal with the situation as team and are able to communicate effectively.
Time is a little bit on the short side and thats another bit pressure put on the applicant. Still better than have an experienced pilot flying raw data VOR Holdings and Course Intercepts or BS like that.
I must say that I agree. The sim eval is overall a basic sim profile that any competent pilot should be able to handle. The challenge does come from, as you mentioned, the varying backgrounds, and ultimately I think that is one of the big factors they are looking at - how well you work under pressure with a person you do not know and has a different background.
