HP Inc. Business Analyst interview questions

Had a phone call with hiring manager and HR. Hiring manager was very impatient and unprofessional. When I was asked about how I do my ad hoc analyses, he sighed, slumped in his chair, and rolled his eyes. To this day, not sure if I really was just that inexperienced, but I don't think any interviewee should have to go through such gestures. It made me wonder just how he runs his team if he was already showing some attitude in an interview.
