I've had very similar experiences with Delphi, Jade and embedded C developer interviews. It makes me wonder why other companies don't actually care whether I can write new code, only whether I can replay algorithms. When interviewing I build a set of simple examples like yours and run people through them, normally in person. How they talk to me is also important. Albeit here in Australia FAANG interviews are mostly regarded as yet another US foible like driving on the wrong side of the road. I've had exactly one attempt in ~10 job changes but they failed (I walked out as soon as they made it obvious that they were serious... but were not offering FAANG money).
