HR coordinated the details of the interview process. Many candidates for same position were waiting in the lobby for a round robin multiple person interview. I waited in a break out room and the interviewers rotated in to speak with me, representing themselves as managers over specific teams. One interviewer , took a very unprofessional approach to my resume and seemed like frustration more with HR bringing me in verses me sitting there across from him. I called HR the next day and made the decision I didn't want to be considered for any position under his team. When HR said he was part of the entire team, I respectfully withdrew my application on the phone.
