Perguntas de entrevista de vagas de IOS Software Developer da empresa Handshake

FIrst Interview was a standard HR talk, questions about my experience, skills etc. Then some information about their company, as usual. The second interview was with their Lead iOS Developer, I was asked to do an online coding in some website form. Of course, I didn't remember all the syntax by heart, but I think I got the idea and came to a logic on how to solve it, then solved it. Nevertheless, I got a refusal afterwards. When I asked why I got an answer that they didn't like my coding skills, because they need me "to write code correctly, efficiently and quickly". I know that I didn't solve just like that in a matter of seconds, but I got the logic right and I solved it. Maybe it wasn't an ideal solution, but still, considering it's an interview and I didn't google stuff and didn't have time to think about it a lot. Anyway, it is what it is, I'll leave it as is.
