A little example of how recriutment in IT works.

Mechanic gets a live mechanic skill test to get a job, as he really wants this job because of lack of money he asks recriuter couple of questions.
Mechanic: do I need to bring my own tools ?
HR: no everything will be provided in place
Mechanic: what would I do during this test ?
HR: everything will be explained just before the test I’m not an engineer so engineer will explain everything to you

The test day, mechainc goes to the test place and the recriuter says:
Recruiter: Your first task is really simple, please tighten those screws, you have 10 minutes
Mechanic: But I don't see the screw driver

Recriuter: I can't say to you how to do it, you figure something out
Mechanic somehow manages to tighten those screws using his belt

Recriuter: Ok so now tell me what force is needed to unscrew them and tell me if you did good if I’d say you need to tighten 1 million screws
Mechanic: I just want to do my job

Recruiter: Hey we are looking for people with broad experience for this position, of course you wont be asked to do that task but we want to know if you’re capable to do the job if we ask you.
Mechanic: answers the question that he will use tools and what devices he will use to measure the force

Recriuter: Can you write this as a mathematical equation ?
Mechanic: don’t know that
Recruiter: Well we can’t hire you we are looking for someone with more knowledge about the topic

Mechanic: But you keep asking me about the fucking screws
Recruiter: Watch your mouth sir because for me you are junior mechanics, you don’t know how to use proper tools and you barely manage to do the first task in time I would use: started elaborating about tools to tighten many screws at a time in a distributed fashion

Mechanic: but to run those tools I would need more than 10 minutes and besides that those are not here
Recruiter: yes they are, we open those doors to get them before our work you suppose to know that and we use those all the time, it was in job description, besides that it is recommended by company xyz to keep those tools behind blue doors, there is nothing here besides blue doors and room with tools and you didn’t know what blue doors are for, you need to learn the basics first

Mechanic resigns. 90% luck 10% skill
Every fucking time.
