I have been given screening test on hackerrank. I failed the test, e-mailed skyscanner asking for testing inputs, because I was sure my solution was right. After providing test inputs, I have pointed out that the specification of the problem was wrong/incomplete and my solution was right according to the specification. But after that, skyscanner is just ignoring my emails. I have sent them three emails, they just do not bother to reply and give me some explanation.
