"It was never communicated which languages the coding test would be limited to before I started it. Those I could choose from were C, C++, Java and a couple of others, which ruined my plans to use Go or PHP - the languages I was the most proficient in. So I ended up choosing Java."

Similar thing happened to me. I was never told or asked which programming language I would prefer. I click the link, filled some info and I landed on programming question with only two choices C or C++. I was like wait?! Though, I tried to solve the problem, but couldn't finish on time. I contacted the recruiter about this and I never heard anything back. All I got was email, Sorry you didn't qualify. I really liked the Hackerrank interface, but I was disappointed in lack of language options I was given.
