Answer 2

"A system integrator company in the job description"
"what you really need to know, who can describe in more detail"
An employee of this particular company knows exactly and can describe in more detail what they are looking for.
You must understand that each company has its own nuances, its own job descriptions, its own requirements for employees. On the toaster they will describe to you the experience of what other companies can have, and this can vary by orders of magnitude.
