2 rounds tech on python skills and leetcode problem, 1 round with Hiring manager on Behavior questions. no OA or homework assignment. leetcode with level easy but put values in optimization

Post the screening round there was a Technical Round which lasted for 1.5hr. Two people took my interview and they asked basic questions about python gave some problems to solve etc. what they are looking for: 1. unix 2. sql 3.python 4. django 5. fastapi it went very well and i got an instance response for f2f interview i cleared the first round and the second Technical round was a F2F interview. The f2f interview is nothing different than online they call you to a meeting room just to connect you to a zoom call. they are rigid enough to not turn on their cameras (its little demotivating talking to icons) and while i was sitting there i realised the interviewer is quite rigid for example he asked me which orm have you used i mentioned sqlalchemy and he didnt know about it he only judged that i dont know about pydantic models and then he told me they are looking for people having more skill set in api development . In the previous interview i had explained my api development answered questions about fastapi and flask but it felt like this fellow hadn't taken feedback from them. i strongly believed he had someone already in mind who he wanted to hire and they just wasted my time calling me there. In the end he said prepare more (without even asking me questions he came to the conclusion i was under prepared) They are a huge company with people being superiority complex. what is a job finders situation today can be theirs too someday.
