I think a very real problem is that these take home problems are often way more than 4 hours. And to that they often add the traditional 4-6 hour interview loop.
Provisional employment doesn’t work for most cases, though. It might attract people who have no job and it might attract people who have so much saved that they are okay with potentially being let go after 90 days. But I imagine the vast majority of the potential employment pool are not willing to quit their current job to accept a “maybe” job from another company.
Adding take-home problems to a traditional 4-6 hour interview loop is odious.
But the "way more than 4 hours" thing smuggles in a premise: that every candidate should be able to finish the challenge in the allotted time. But candidates with greater aptitude or conversance with the problem domain will complete work sample tests faster than candidates without, and selecting for those candidates is the point of hiring qualification.
It depends on the details of the work sample test.
If I ask you to write me a python function to convert OSGB easting/northing into WGS84 longitude/latitude the task has a very clearly defined scope. If you knock it out in a quarter of the allotted 4 hours, you've saved time. You can't use the remaining time to go further and demonstrate your mastery.
On the other hand if I ask you to write me a website for organising photos, there's no such thing as 'done' - no matter how good you are, after 4 hours you'll still be able to think of ways to make it faster, more beautiful, more featureful, more scalable, cheaper to operate, etc
Obviously, as a hiring manager I'll notice if you've spent 40 hours on the 4 hour task - but if you've spent 6 hours maybe I just think you're a fast worker with relevant experience and sharp tools. And my sense of how far you can get is calibrated by other prospective hires; if lots of people are spending 6 hours and claiming to have spent 4, my expectations will naturally be high.
Again, the premise is that you're exercising professional judgement. If you can't let a project go until it's perfect to a standard far past what's called for, that is itself signal. Either way: if the project budgets 4 hours, it is on you as a professional to stop at 4 hours.

This is theoretically true but it’s also rife with misaligned priorities. The people putting together these take home assignments have little incentive to ensure that they can be completed by a competent engineer in the allotted time. The engineers completing these assignments are definitely incentivized to underreport how long they spent on the assignment.
With AI coding this is also largely useless. These “build this thing in 4 hours” assignments come with a literal prepared prompt so that they can be churned out in 10 minutes.
We don't ask or check how long candidates take. You're a professional, we give you a challenge, you can decide (up front, 30 minutes in, whatever) whether you're likely to be able to finish in the budgeted time. Maybe you can't because you've got a lunch date and don't have the contiguous block, and want to do it in chunks. Fine by us.
Again, the underlying smuggled premise here is that candidates have to finish the work sample. No they don't. In fact, that's a strong sign it's not an effective work sample. A test that everybody passes isn't a real test; it's just a hazing ritual.
