Canva Senior Software Engineer interview questions

Their recruiter sent me a message with a code challenge link to a platform called "HackerRank". I was supposed to solve a "find contiguous sub-array" problem in 60 minutes. I make it pass in 7 test scenarios out of the 10 in less than 60 minutes, so I decided to just submit it as it is. 2 days later I received an automatic message from HackerRank saying that I didn't meet the requirements for the job. So I replied to the e-mail with the recruiter in copy and they didn't reply. After one week, I sent another e-mail asking for feedback in order to understand what could be better. I received a response like "All I receive from HackerRank is that you didn't get a high enough score to pass the test. Sorry mate, good luck on your job search!" Are you guys really basing your recruitment process on "scores" of a 60-minute puzzle? That is so 80s... I thought at least I would have more serious feedback or another round of discussion so other aspects of my experiences got analyzed. That hiring process is so broken, that if I already have had solved this very problem before, you wouldn't even notice and I would pass with a maximum score. That is pointless.

Disastrous interview experience for both sides: First screening interview (20min total) - The interviewer started the conversation by making clear that other technical positions were more important than the one I was applying. After being asked to be honest and disclose what I have on the table, they got angry to know that I have other offers and made it clear that I should not waste their time going any further.
