Who are Rockstar/Ninja/Guru/Wizard/Jedi developers?

Question

Freelance

On elance and upwork, I often see that clients write that they want some kind of Rockstar/Ninja/Guru/Wizard/Jedi, for example, Ruby on Rails developer.
What is this nonsense, or does it mean something?
How to understand who I am, maybe I'm a rockstar or already a guru, but not yet a ninja? Is this some kind of meme?
I always laugh at these words in the description.

Answer 1

The terms are equivalent, used to refer to very cool pros.
Everyone uses the term that he likes best. Like if you're a Star Wars fan, you're now a Jedi)

Answer 2

Become a Ninja, you'll know.
In general, if you do not have the necessary skill, you do not need to respond to work. If they're looking for a Jedi or wizard with programming skills, and you can't swing a lightsaber, you're clearly not the right fit.

Answer 3

And I'm always out of work...
-- Senior Sith Developer

Answer 4

The main thing is not to look for Jedi on the salary of R2D2.

Answer 5

When you look at their requirements and understand that "generally easy" then you are Rockstar)))
