We are very sorry to hear that you made a bad experience in our recruiting process. Our Hackerrank test is a very short basic test of technical skills. Since we are dealing with plenty of applications and processes, we will provide detailed feedback after our hiring manager call and definitely after our panel stage, which is the last step in our process. This feedback is always delivered verbally. Regarding the infrastructure role, we checked all results in August 2022 again, and there were only tests with 70-75% achievement score.
