Neustar Software Engineer III interview questions

Regular interview questions asked on programming logic, Spring and design patterns. This interview went well and Panel told me to sit and I will call another panel for the second round with me. After 5 minutes, he came back and told HR is on leave and told me to leave for the day. I called the recruiter immediately and she told that interview did not go well. It is really surprising to know Neustar has TWO TONGUE. They can't give the genuine statement. It clearly indicates, how to be unprofessional. Great going Neustar.
