The Dash needs rudder trim frequently throughout the flight due to the effect of power changes. Using the rudder pedals to maintain the aircraft in balance whilst making initial trim adjustment is quite normal. For minor adjustments in cruise, a shirt 'flick' of the rudder trim control is all that is required.
Some of the company's lazier pilots don't bother. They'll quite happily fly an out if trim aircraft all day long. There is also some nonsense peddled by certain individuals that you shouldn't use the rudder pedals in flight and as a result, some pilots are reluctant to use them as they're convinced the fin will snap off.
Rudder control on the aircraft is very effective, due to a long moment arm and a large control surface, but gentle rudder usage in flight is a non-issue. The best way to treat the pedals is to apply nothing more than light pressure, rather than a push. None of the aircraft controls require agricultural handling (but you'll still see it), but the rudder requires an especially light touch.
Either way you choose to fly it, for an initial sim assessment, I doubt they're looking for that kind of finesse. Safe and competent, with an ability to take instruction and show improvement throughout the profile is what I expect.
