I am seeing a mild deficiency in energy management, as well, but it's wider than just new-hire pilots. I would say that the primary flight training pipeline is still too maneuvers focused, and pilots who don't have substantial "doing something other than following the student->instructor pipeline" flight time tend to be missing a certain something when it comes to piecing it all together.
That said, by the time pilots are about a year in at a regional, they seem to mostly get it IF they care. (And most do. And I'm going to tell you straight up, I have some wicked good FOs. Like my current one, coming up on a year, who I'd say is basically ready for upgrade.)
What really shakes things loose for these newer pilots is when the program no longer works. Not "let's modify our plan, go higher, lower, etc", but "The plane just decided to turn left instead of right on a tight ODP in mountainous terrain while IMC, and it wants to fly into a mountain. Your turn!" (Hint: heading mode isn't the answer)
The funny thing is, though, once they experience stuff like that a few times, they tend to lose their blind faith in the magenta line quickly. And it makes them verify more, verbalize more, and react better.
Anyway, I guess what I'm saying is that the kids are alright. They're learning from experience and flying competently (at least at my carrier). That said, since most FOs are under a year on property at this point, those events where experience is gained occur more often.
Heck, I dunno. I just work here.
