I've met the hr and had a typical chat. I cleared that stage and I've received a coding test on one of the platforms that checks your skills against a timer. It was 3 problems, quite accessible although not the easiest. I've solved them all way before the time elapsed and all the tests(visible) were passing. Several days later I get the email from the hr that I did not pass the coding challenge but that she's open to discuss it. Im perplexed, as I've solved all 3 problems so I ask a few questions, waiting to get some clarity. I got ghosted, never received an answer
