Take-home assignments that clearly need 8+ hours — do you eat the time or push back?

Got a take-home this week scoped as "2–3 hours" that is very obviously a full weekend if you do it properly — auth, tests, a real README, deploy.

Do you do the bare minimum inside the stated time and just note the tradeoffs in the README? Do the whole thing and hope it stands out? Or politely ask to swap it for a live session?

I've heard "never spend more than 3 hours on a take-home" and also "the take-home is where you actually win the offer." Both can't be true. What's genuinely worked for people here?
