EMCOR Group Business Partner interview questions

Honestly the interview process was very awkward. The first round very rude and cold in the interview. She did not really explain the role and department, and just started the interview with "I have a lot of questions get ready". She seemed to get annoyed when asked basic questions like, what is the department like, or even, please tell me about the hiring manager. It was not a great first impression for this company. And it seemed to get a bit more tense when I finally met with the hiring manager, and she essentially did not even believe me when I told her I was not told about the department or even more about the role. Just overall an uncomfortable experience. Hope the director was just having an off day because that is NOT how you conduct interviews.
