One of the major problems with take home tests is the rampant cheating.
It's been a long time since I've been on the job market - but even a decade ago, I had third-party recruiters who would forward me a take home test... and another successful candidate's solution, "for reference".
And even if candidate doesn't get external help, I'm extremely sceptical about time limits. Nothing stops someone spending 6 hours on a "2 hour" take home test, producing a better solution than someone who followed the time limit strictly.
It's pretty hard to extract a signal under such circumstances. Unless you're hiring for a job where a willingness to bend the rules to get results is desirable - used car sales, for example.
