Alignable Software Engineer interview questions

The process started with Terminal.IO they were very helpful in starting the process. There was no contact with anyone directly with the company, just only with Terminal. Alignable sent a code challenge over hacker rank, in which I passed all these tests, I agree they can say I'm not selected and this is ok, but the only feedback I received was: "the code was not strong enough". Is really bad you spend a lot of time just getting a few words.
