> You are prone to quixotic behavior.
They are looking for people who are prone to irrational, unrealistic behavior? It makes for nice prose but I have a feeling that some of the personality disorders that could be described by their phrasing wouldn't be particularly welcome.
> Full-stack.
What stack?
No really, you're hiring me for the full stack. What is the stack?
Would I ever be writing a line of CSS? Or JavaScript? Or Ruby? SQL?
At least they say "Largely PHP" a little bit later, but that makes me wonder just what their definition of full-stack is.
I appreciate pleasant writing for the sake of it, but there's a lot of information they could have imparted but chose not to. I wonder if they'd respond favorably if I actually replied in kind. Do they really want quixotic behavior? Is being scant on technical details an OK thing for a technical job posting?
I'm tempted to send a cover letter talking about how the best CSS (would I be writing CSS?) is made with oil paint and that I wear a tea cozy for a hat. I could claim to have independently discovered punctuation and talk about how I navigate code by wind chime.
