Fist you will get a call from a recruiter. This usually goes smooth, but they will ask all the typical questions. Remember they get paid if you get hired - so they will give you advice for the one on one interview. The one on one was obviously harder. They will drill you about why IT sales, how did you hear about the company, give an example of an open ended questions. All that good stuff. Be prepared to ask as many questions that they asked you. They will want to know that you are interested and took the time to do some research.
