Is it appropriate to interview the employer in an interview?

Thank you for your answer Nasrim, I have been doing some research on this and it seems to vary from country to country. The understanding i am getting is that some places are more male orientated than others. So i shall bare this in mind. 

I guess no because you must be carefull of what you say in an interview you will only ask at the end if he gave you the opportunity to ask about somethings
