BNP Associates interview questions

There was a Zoom meeting centered around salary negotiation per the interview process (the president of the company joined in on this call). I tried to negotiate a higher starting salary, but settled for the original offer. Shortly after, the president went on a long tangent regarding an unrelated topic, and then terminated the interview in an extremely unprofessional manner.

Very unorganized. 3 people involved, including 2nd generation owner. Position advertised on Craigslist, and does not include any salary information. After 2 interviews the salary details were still clearly undecided upon. Owner ask demeaning questions like, "would you be willing to clean up his office while he is out of town". The company presents itself professionally, until the owner got involved.
