League Senior Software Engineer interview questions

The technical interview was with two engineers. And I felt the engineers were not too aware of how the application security and related tools (SAST/ SCA) work. Overal,l it wasnt a pleasant experience for me as due to their inadequate knowledge I felt like I wasnt selected although I answered each of their questions correctly. When the Director of Talent communicated the result to me I asked for the exact feedback from the last interview or the exact reason for not getting selected. I even requested to provide my feedback on the interview. But there was no response after that.

1) Coding challenge 2) Architectural challenge 3) Technical interview 4) Arch. interview 5) ?? I was told coding challenge was impressive then asked to complete architectural challenge within 24hrs. Process abruptly cancelled after the technical; so I spent time on architectural challenge as well. Developers looked unprepared and hinted that they learn from these challenges. Seems companies are not really hiring and using candidate interest to keep their current staff abreast of the latest tech this way
