CommScope IT Audit Senior interview questions

The interview process was less than 15 minutes with HR lady-who was rather too much in a hurry to get me off the phone the moment she heard my voice. I was never given the opportunity to ask any question. The moment she got my responses she just said I'll pass your information to the hiring manager. Three days later she sent me an email that they have decided to move forward with well qualified candidate. I have never replied to any rejection letter before in my career pursuit but I replied to her email that I was not satisfied with the way she went about the interview...She replied by saying she gave me the chance to ask her question which I never did. I was surprised when she put forth that defence but I never wanted to be involved in that kind of arguement with her so I decided not to reply her. It was an awful experience!
