Why are there too many requirements in the vacancy or are these standard requirements?

Question

Career in IT

Hello! I'm new to habré, but I've been following the site for a long time. I have a question.
I work in government organizations as a site moderator. I know HTML5, CSS, I study PHP, JavaScript. The salary is below average. Today I flipped through HeadHunter to look for a more prestigious job. Looked that, almost all employers require too much knowledge, an example for a couple of vacancies. The following requirements are written there:
1-vacancy
Experience 1-3 years
Responsibilities:
Development of integrated solutions for automating business processes
Support for existing projects
Requirements:
Knowledge of .Net Framework 4.5+
Development of web services (SOAP, JSON): WCF, Web API 2.0, ASMX
Windows Service Development
Integration with APIs of third-party systems via protocols (SOAP, JSON). Use of third-party SDKs
Minimum C# programming experience.
Experience in writing technical specifications for software development will be a big plus.
Experience with ASP.NET, NHibernate, JavaScript will be a plus.
Work with DBMS MS SQL Server 2008+. Experience in normalizing/optimizing the structure of the database and optimizing SQL queries is welcome
Experience with any ORM: NHibernate 4+, Linq2db 10+, Entity Framework 4+
Experience in deploying automation solutions on servers
Experience with any VCS (version control system ): Git, SVN or similar
2-vacancy
Experience 1-3 years
Knowledge of technology: HTML5, CSS5, JavaScript
Strong knowledge of any JavaScript Framework: ExtJs, DevExpress for HTML5 or similar with a rich palette of visual components

Experience with any CSS Framework : Bootstrap, Uikit or similar
Experience with any VCS (version control system): Git, SVN or similar
Experience with Linux, nginx, Git;
Development experience with Laravel framework;
And the question is, can one person digest such knowledge in the brain at all, or does employers require too much from a candidate, or is this a standard requirement?

Answer 1

"by position moderator of the site"
Your position as a moderator, in theory, has nothing to do with the development.
If you didn’t moderate for a year, but wrote code, it would not be difficult for you to learn any js framework, css, gain experience with VCS, with git, and so on.
The vacancies list the average requirements for a confident junior - a beginner mid player.

Answer 2

Pretty normal requirements.

Answer 3

Pfft, that's not much. Look at the vacancies of php-nicknames. That's just Hell and death.

Answer 4

It seems that they don’t ask for anything unusual, in the first case they ask to know the dotnet and actually you need to know Sharp and the microsoft framework for it, you can quite briefly describe this vacancy like this.
Everyone should know Git, a developer cannot write complex systems without Git in principle.
In the second post, to know something from the html js css stack, as if without this the front developer could not do it and any front developer knows this
Where Laravel is screwed in is not very clear

Answer 5

These are not mandatory requirements.
And desirable.
No one will demand 100% of your compliance.
All in all, they are just tools.
You can type letters on the keyboard.
So the knowledge of these tools is the same basis.
It will be a plus if you know not these tools themselves, but their analogues.
