Preguntas de entrevista para el puesto de Full Stack .NET Developer en Siemens

The first round was technical round on teams. Interviewer was very knowledgeable. Asked wide range of questions from Web api, EF, design Patterns, solid principles and few puzzles. The second technical round was also on teams. The interviewer was very dull and sort of unprofessional and no knowledge of software whatsoever. Seems to be asking questions from internet and expecting the same answer on internet. No challenging stuff, the regular string manipulation problems to be solved on notepad. Answered well and even verified my answers post the interview and everything was good. Disappointed with the result but I feel sorry for the people working under that guy.
