That’s a fair point.

I think that in the specific case of Stripe, they specifically mostly use Ruby (from answers I found online). I may be wrong, but I assume that not mentioning Ruby is a way to attract Python/Go/C/etc. developers that might otherwise think that since they don’t code in Ruby, they shouldn’t apply.

Your main point (re: Java) remains of course.

Not to pick on Stripe, but why not say this explicitly?

"We mainly use [language X], but you don't need experience in [language X] for us to consider your application" - this is a totally normal thing I've seen in many job postings.

I agree.

Stripe is sometimes more explicit about it:

https://stripe.com/jobs/listing/infrastructure-engineer-ruby...

"Our most popular language in the company today is Ruby, and we are building a new Ruby services practice in support of this."

... but that job is also an openly Ruby-centric job.
