The complete overview...

(right-click and open the picture in a new browser tab instance if needed)
Here it is! For those who follow. This is my vision ( Valentijn Peters ) of what types of software testers there generally exist in the field.

In the top there are 2 categories namely frontend and backend oriented software testers. 

The frontend of the software has it's own particullary test tooling. And the backend of the software has also it's own particullary oriented tools.

Both have their foundation, which is the underlaying programming language. Which in it's turn is mostly based on the fact if it is Operating System or WebBrowser related.

Anyway, when I see the applications for a software tester on several websites who scope for a good tester I literally burst into tears.

This picture I scetch is so far far FAR away from their knowledge about software testing that it get's really frustrating.

some examples like:
- Junior, just  graduated with 10 years of testing experience.
- UAT tester with Backend tooling experience.
- Selenium expert with Cobol knowledge
- out-of-the box thinker, creative and also helicopter view and very accurate.
- High level of soft skills and very focused on details and prefers to work alone.
- 10 years of frontend and 10 years of backend experience, but low hourly rate

and other examples in the same category:

Please people STOP!
Gain some common ground about what it is that companies need for type of software tester. And stop spreading applications for testers that don't make any sense at all!

First: determine what it is that you exactly need!
Then delete all the catch-22, ambiguity and stupidity from the application. 
And only then see if you can find your perfect tester!

And  while you do this, keep in the back of your mind: 
It's NO fun playing chess on your own! 
(In other words, is it really only 1 tester you need?)
