Planet Senior Product Security Engineer interview questions

First round was HR assessment followed by technical round. Technical questions are very basic, nothing sort of difficult, interview was done by a non-security engineer who a part of cyber security team was not. I am not sure if my answer was well understood by the interviewer, not sure how they made a decision to reject. This is the easiest of all security interviews I have attended. Someone with Security experience in 4+ organizations over 6+ years and holding OSCP, CRTE, AWS, etc etc can tackle this interview without breaking a sweat. I don't know how they made a decision to reject me, it was surprising. No doubt they keep interviewing for same job role for months and years, wasting everyone's time.
