At the risk, otherwise, of having a thread with 400 catty comments ..
(a) for a first jet endorsement, there is a general tendency for the new pilot to be a bit heavy handed with significant overcontrolling being the result.
(b) it may be useful, at the start, to try the two-fingered technique to force the pilot to use a light touch on the control wheel.
(c) after a while, one finds that the pilot gets the hang of what is required and reverts to a normal grip .. but with a light touch.
I suggest you don't sweat it too much .. things will start out a bit difficult to catch up .. but it all settles down after a few sim sessions ...
