Several days ago I had a job interview. I asked the budget of the project and they did not answer the question and asked me why I was interested in. I just said I was curious, because I was curious. I could not give am more elaborate answer because I did not expect they would ask me why I was interested in learning the budget of the project.
Is it OK to ask about the budget of the project in the interview?
How should I have answered this question?
A side question: is it fair to answer an interviewee with “why are you interested in learning this?”
