DFS Group Finance Manager interview questions

Job title wasn't the most accurate, job listing wasn't very detailed. HR person A.O. only shared more on what the job entailed after quizzing me on what the job scope was. She shared more about the job scope - which subsidiaries it could possibly entail. I enquired further about the stores to understand the scope of work, to which she replied "you're really testing my memory" which left a bad taste in my mouth. She also told me to go check it out on their website, which would be fine except for the prior comment. She also scoffed at my answer when I talked about my weakness. I had higher expectations from this company, but I wouldn't have wanted to work with someone this unprofessional from the get-go.
