When I was open to new job opportunities, I immediately turned it down if the job description included words like rock starts, ninjas, etc. I am not against the mindset. It is just not a good fit to my personality.

I want to work on products that I consider meaningful and work with good and serious engineers. It is nice to hang out with colleagues, have drinks, saying jokes, etc. I am a big fan of classic rock. But calling engineers as rock stars, ninjas, etc, or engineers labeling themselves as such personalities, really convey a somewhat negative impression to me.
