Infectious Media Software Engineer - ETL interview questions

There were 3. CTO and two developers. Most of the interview was related to the processes at my current workplace (how wrong are our processes) and they didn't care too much about what I know or what I want to do. The two developers were almost laughing about me not knowing to answer to some their questions. Quite arrogant in asking or replying. They asked at least 1 year of Python and instead they were expecting a mid to senior developer. Very unmannerly way of interviewing a candidate.
