Take-home assignments: how long do you actually spend on them?
Got a take-home that says "should take about 4 hours." I spent closer to nine because I kept polishing tests and writing a README nobody asked for. A friend told me I'm sabotaging myself and should timebox hard, ship the boring version, and move on.
Where do you draw the line? Do you do exactly what's asked, or add the extra polish to stand out? Curious whether the polish ever actually gets noticed.
