Actually, I didn't get a interview. I applied to a Frontend Engineer role at Company's site. Some days after, at apr 30, I received a e-mail from a HR recruiter, telling me that my skills matches with a Backend job. So he sended a question to be solved in any language within seven days. I took 5 days to solve the problem, and I was really giving my best effort to deliver a correct asnwer and a clean code. At 6th day, when I was about to send my answer, I received an email, telling that they "did not hear from since we sent you our small coding challenge over a week ago". That was very frustating. I still had one day to deliver my answer and now, I can't even apply for a backend role, because the Recruiter did the application himself.
