What are some good questions to ask at an interview?

Well you have to be prepared for this interview, its not about asking questions only! you have to be prepared on the way you should answer,be well prepared/get on time/smile all the time/eye contact/never answer yes or no! always explain/shake hands firmly/self confidence/know the company very well/never ask about sallary unless they ask... about asking questions, try asking something about this job and you need to clarify things and you are interested in this job,common question you maybe asked are: 1) tell me about yourself? 2) why did you leave your last job? 3) why do you want to work with us? 4) where do u see ur self in 5 years? Good luck and remember to be MOTIVATING!
