That's certainly your prerogative, and we all have to draw the line somewhere in terms of interviewer demands. Personally a reasonable homework assignment (like 2-3 hours tops) is less annoying than multiple 6+ hour interview panels stretched out over a period of months, which is also very common. At the end of the day though, the company decides the hoops you have to jump through if you want the job, and you can either take it or leave it. FAANGs can get away with onerous processes because of the technical brand and outsized comp, but startups and lesser known companies who try this are shooting themselves in the foot.
