Once upon a time there was a dev.
The dev had a resume that said he could dev.
We called the dev, he sounded intelligent.
We hired the dev, who was a bit green, on a three month probationary period.
The dev did very little.
When asked, we said he contributed to discussions, but seemed unclear about what to do, and maybe they could keep him as an intern if they wanted to have him at all.
They hired him. As a full time dev.
6 months later, that dev was shocked to find we could log into the servers with a privileged account.
We (his team mates) were sad.
We asked him to fix a few prod errors.
A little while later he said "Done!"
We then had to walk him through how to actually fix them, not just add a couple pieces of info to the table.
We were sad, again.
We asked him to fix some prod errors again.
We had to walk him through the process again
We expressed concerns to our superiors about his abilities because he was all theory, no hands on ability
They promoted him
We were sad
A few of us said "Fuck you guys, I'm going home"
They said OK
Now that guy is the only one that "knows" that code base
I get calls sometimes asking me questions.
I told them to pay me a consultant fee.
They said no
I said no
They called again
I laughed at them

Listen to the people who know when you ask them questions.
Listen to the people who know when they tell you there is a problem
Don't be like that company
