Luno interview questions

I recently gave Luno's Hacker Rank Test after practicing over a week and then only response i received "we’ve ultimately decided not to proceed to the next stage of our process", though i feel it went well. It would be nice if at least you can share results or some suggestions

Long and in some cases unnecessary. Too many interview steps all asking the same question. It can be made shorter by organising a panel interview. Overall the process was not arduous, juts inefficient
