Why do we have to put so much effort into job hunting if Employers can just not even respond to our application?

Why should a programmer have to go through 200 questions, a programming test, have a github portfolio, a website portfolio, a custom cover letter. ONLY for an employer to not even give a call back or a human email saying they were rejected?

Oh and if you just try to simply submit your application and refuse to do these bullshit ass tests/portfolio then people think you’re lazy. How the fuck am I lazy for not wanting to throw hundreds of hours of my life away on this bullshit job application process.
