I got my current job due in part to 400+ hours of 727 Level C/D sim experience, more than half of which was in a major 121 training department.
What documented simulator training does show is experience in turbine aircraft and high altitude/high performance operations...and that with your complex systems knowledge and simulator experience your risk as a newhire completing training would be slim to none. That is the angle you take when asked on it...you are completely confident you will complete training based upon your past experience! It won't get you hired at places with very hard TT minimums but it will get you hired at other operators.
Its like the old saying about having 1500 hours or 1 hour logged 1500 times.
