About the simcheck and evaluation, as far as Im concerned, they want to see if you can fly. They are not expecting you to ace the techincal aspect of the flying.
What they do expect to see is good CRM and a good attitude. You have most likely never met you simpartner but still you have to be able to work like a team, sounds simple but can be hard as we all know.
This is valid for most of the airlines about, crm crm crm crm crm and attitude, and top that up with sound and reasonable flying.
my two cents...
