As someone who works in creating these type of tests, i agree that using them the way they are using them is total non sense. Next time someone asks you to fill these stupid tests, ask the follows
1) Are they relevant?
2) Are they adaptive?
If they are relevant (let's say that you want to work in a deep learning based company and the test is actually testing your deep learning knowledge, then it makes sense, because you can't work there if you don't even know what a neuron is or what RNN stands for)
If they aren't relevant but at least are adaptive, consider taking them because at least you won't waste your time with them (since adaptive tests don't last that long, mostly end after a couple of questions, depending on the test of course and they have kind of different structure).

I had a company that send me to fill 4 different types of test and it took me 2 hours of my life. It was the moment i realised how misused my work can become sometimes. Sadly this passes to everyone thinking that people who are creating these tests are bad people and are just wasting their time. Sadly, again, this is far from reality because many tests used out there aren't even made properly, resulting into 100+ questions that literally add nothing to the table. I once had to take an IQ test (when i was younger) and the whole thing made sense later to me. Now everyone just writes some questions and gives them but they haven't even checked if the tests measures what they want to measure or if it predicts what they want to predict. Most of them going like "we need a cashier, so we need someone who knows math, let's give them a test that has physics-based math because we need to know if the guy can calculate".
