This is what I don't care for, because it doesn't mirror the job at all. If it takes someone 20 hours to do a 3 hour project, that's a problem and it won't show up in the takehome.
It's almost the opposite of what the job actually entails. I rarely estimate that a project will take 3 hours and then I have 48 uninterrupted hours in which to accomplish it, no biggie if it takes more than 3. The job is typically the opposite, where I estimate it will take 3 hours and then I realized that I need to accomplish 40 hours of work in the 20 meeting-free work hours I have this week so I need to find a way to finish it in 90 minutes.
