FAA stopped publishing questions over 10 years ago. Whilst question banks now are common for FAA (just like EASA) the question are periodically reviewed to comply with airman certification standards. That means that questions must be specific, relevant and enhance safety.
I took the FAA ATP exam a few years ago and whilst it wasn't overly difficult, the questions were relevant and things you need to know.
Unlike EASA who seem like they want you to know the voltage of an A320 flap actuator!
