Do you want to ask about me or company

Don't ask about the company because that might give them a bad impact that you are not researching about the company that you are applying for. Maybe an exception is to ask what are the technologies they are most used but nothing beyond it.

Instead you could ask about the interviewer itself about the technologies and the working environment ~ stuffs like that. This will help you visualize yourself when you are in the team.

PS: Don't ask about salary or working schedule yet because you are selling yourself at this point. Instead sell your technical skills and tell more about your experience and the cool things that you've done in the project.

This is just my opinion ;)
