Whilst the simulator part of your test, just good flying skills doesn’t guarantee your seat in one of the good airlines. This is why usually people take a course named MCC in which you learn how to behave in a multi-crew environment. So during the test when you are the PNF, assist your PF in every possible way and while given the role of a PF, engage your PNF in some task as well. In airlines, you should know how to handle your team. Otherwise, this could cause havoc in your time of flying. Hence, a good display of crew resource management plays an important part in this as well.
