CC, reading between the lines of your post, and assuming you did ok in the sim, then I'd suggest you said or did something that upset the Human Remains (HR) oxygen thieves.
These leaches have over the years got their toxic influence up to such a level that they often have the ultimate say so over if get employed or not.
It will mostly have nothing to do with you being able to do the job...more likely they have assessed that due to you not being able to weave a basket or perhaps convey a time when etc etc...you are in fact a closet axe murderer, or display latent pedophile tendencies, and are thus more suited to a role in HR, or revenue management
