What do golems look like?

I am not talking about the Dungeons and Dragons type of golems but the golems from Jewish tradition. Do they have the appearance of an animated statue or something which is vaguely human but decidedly not upon further investigation?

My question stems from the X-Files episode “Kaddish” which involves a golem, except the golem central to the plot is indistinguishable from a human except when deactivated (been a while since I watched the episode).

Was thinking about writing a story where an orthodox kid in Lakewood creates a golem and was curious as to how human/inhuman a golem can appear.

Thank you
