As someone who's already employed, if someone asks me to spend more than 30 minutes doing an assignment or test before an interview, I'm just going to pass. My experience has been, 95%+ of the time when I do the test or assignment, I don't even get an interview (much less an offer). It's even more ridiculous because I really know my stuff; at my current job, I do all the tasks where someone else gets stuck. Suppose you hire 1% of the people you interview, and you expect them to spend 10 hours before the offer. You're wasting 1000 hours collectively (half a year of work) of your candidates' time.
