Dumbest experience.
Talked to recruiter, they praised I know ruby, said I needed to do a code test in ruby.

I was given 1 hour to complete 5, exercises in a codefight like thing.

1 exercise had C as the only lang option.
2 more had C and Python.
The last two has ruby too, they were permutation exercises that never completed within the time restriction (that was probably on me, but they did complete on my local ¯\_(ツ)_/¯ )

I told them about all this, I failed, no second chances, no explanation, no nothing.
