You have about 2.5 to 3 miles to figure out the hold entry while you are turning towards the VOR

Or about one FULL minute.

Biggest errors were not entering the hold correctly

Ummm.... isn't that private pilot IFR stuff?

The sim is challenging, but you are not flying the SR-71 or the U-2. It is a turboprop flying at TP speeds... or roughly 1.5 times the speed of a Seminole on final (about the same speed a 400 series Cessna flies the approach). If 180 knots is too much for you, well..... you finish the sentence.

It all goes back to the PTS standards: control of the aircraft is never in doubt. Yeah, you might bust an altitude, but if you catch it within a couple hundred feet and make a positive correction, it should not be an issue. The same is true for busting a flap speed. Assuming the rest of the ride is good.

Entering a hold, procedure turn, or compliance with approach altitudes is basic IFR. It doesn't matter if one is flying at 100 knots or 500, a fix is a fix, the entry is the entry. Most CFIs who have done a fair amount of instrument instruction can fly a hold in their sleep (I know, because I spent about 10 percent of my instructor time dozing off).

I am not calling out anyone, but I can honestly say when I have flown a sim in an interview and botched it, it was because I flew BADLY that day.

(For the record, the toughest interview sim I ever flew was a personal computer sim used by a FedEX feeder: no motion, no "feel" of a real aircraft, and didn't represent any real airplane, but it did test one's procedures)
