Perguntas de entrevista da empresa IT Managers

Got a technical interview round here, and my first impression is that the one who conducted the interview has no background in the industry or the position that I am applying for. Due to that, there is no clear or correct answer except for the definitions that you may able to find online instead of basing it through experience, examples or implementation, and correct scope of the questions. Got ghosted afterwards

There were 2 rounds, one technical and other HR. I didn't clear round one. I was asked DSA and DBMS questions. DSA question was normal level but in DBMS I was asked to draw diagrams of system architecture and flow diagrams
