Despite what recruiters think, despite what you might think, you are not a language.
Years of hacking have sharpened your mind, your instinct, your reasoning, until you no longer even see the code: you see the answer. You are a problem-crushing warrior, an architect of logic.
So why filter your job opportunities by ‘language’?
I’ve seen this over and over: otherwise smart developers passing on great opportunities because the code-base isn’t written in their language du-jour.
When you seek a Ruby job, you’ll find a Ruby job. When you seek a great opportunity, you’ll find a great opportunity. What is it that you actually want?
Don’t let your love of one piece of the puzzle narrow your career. Seek the best opportunity, and focus your reasoning through whatever lens/language gets the job done.
The best companies hire the best thinkers, and the best thinkers pursue the best opportunities. The rest is just cosmetic.
