I'm just going to leave this here since you're judging his sim partner to be weak. I also think its pretty ironic that it deals with your current employer.

His training records showed that, even though he completed all entry, training, and operating phases without a failure, the captain had experienced continuing difficulties with aircraft control. For example, during simulator periods 3 and 4, the captain was graded unsatisfactory in “approach to stall – landing configuration,” although he received a satisfactory grade in later sessions. During simulator period 7, the captain's altitude and airspeed control was unacceptable, and comments included, “airspeed more than 10 knots below Vref + 10. Fly correct airspeed!” “airspeed 10 knots below Vref crossing threshold,” “gear remains up during entire approach,” and “repeated deviation from altitude 200-300 feet.”

During simulator period 8, the instructor noted, “basic attitude flying cause of repeated deviations,” “constant deviations up to full scale on glide slope,” and “additional training required.” All maneuvers were graded satisfactory the next day (by the same instructor as the day before) during an extra ninth simulator period, and the simulator checkride was completed that same day.

(Bolded items interesting)

The captain completed his IOE at GIA in 34.8 hours, and training captains made several positive remarks, such as “good progress,” “getting better,” and “good job, signed off from IOE.”

However, the director pointed out that, to be hired, pilots must have at least three letters of recommendation from captains in their file, and no such letters were found for the captain.

Good pilots have been washed out of the ranks at GIA/Silver that shouldn't have. Some in my own classes and they're now at other regionals. Silver is not some Mecca where only the best brightest pilots make it through.

@Pilotmechanic I'd brush up in a Frasca 142 (something set up as a twin to help you adjust to the faster speeds) and get your scan back in order. You'll do just fine in training you're already used to the fire hose of airline training. If you can manage your current job and flying I think you're golden and I'd do it too! Nothing beats being able to fly and still have a decent income.
