This is the question from your field. Just recite all the types of bills and then stop. I warn you that you should use the professional words. If you will use layman words then you will make the recruiters confused. And believe me that once the recruiter will get confused then he will do nothing but just make you pay for it. So feel free and just give the names of all the bills which you have studied during the graduation or you have come across during the previous job. But you need to know everything about its.
