HR person was a very odd and difficult to work with. They asked for a time frame which I provided only to have them schedule something outside of that time frame. When I emailed to address the time conflict they rescheduled me twice without notice or confirmation. When I reached out to ask them about it I was treated as an inconvenience. If they were having a bad day why take it out on your candidate? I felt like I was respectful throughout the entire correspondence but treated as if I was purposely making their day more difficult.
