I would like to react rudely to that 4+ hour applicant process. I wish they would come up with a better solution to hiring.
Perhaps that company is only doing this because they have received an untenable amount of applicants who are unqualified.
So the truth of the situation seems difficult for everyone.
My advice is to vote with your feet and find a company where it's right for you.
Find a company where they have virtuous solutions to the challenges of the current world. And then post about it here because we all need to build on other people's good processes.
