Daugherty Business Solutions Software Engineer II interview questions

I was interviewing in their St. Louis office for a position in Atlanta, GA. I have told that the will be a 3 step process. First I had a f2f interview with their HR representative. it was all about my background and the technologies I have worked on and the next day I met with a Senior(Lead) Engineer and had deep technical interview. I have tried to answer all the questions he asked me. Mostly he focused on Restful API. Everything was so good. After I finished with him, he told me to wait for the HR representative. Then she came in and told me that i did great on the interview and told me that they will pay me 10k less than the salary I initially asked and she will going to set up the 3rd interview with the management in Atlanta if I am fine with the offer. I didn't accept it right away. I told her that I need some time to think about it and left their office. The next day I let her know my agreement via email. She replied me and told me that she will set up Skype meeting and never heard back. After couple of days I reached her via phone and she told me that she is waiting a reply from their Atlanta office and will let me know once she got confirmed. I waited for a week and sent her email but I haven't got get any reply since then.
