Frage im Vorstellungsgespräch bei NeoSOFT

First round was pretty straight forward normal python questions, Fast api questions from interview bit types. second round is in depth technical questions from resume and 3 sum DSA problem and a SQL query for finding employee and there manager from single table. last Managerial round was again in-depth project explanation, the VP was not ready to accept that I was included in architect discussions to make LLD and all was very adamant on proving that for 3 years experience you can not do all these things single handedly.
