PIP home visit

Hi there, first post on B&W, please bear with me. I recently had a PIP f2f home visit Assessment, it lasted from start to finish 31 minutes is that the norm. I was asked about my old (years ago) medication, which i had forgot to list historically on my PIP Questionnaire for approx 5 minutes, but had supplied current medication list with Questionnaire, questioned on medication for approx 7 minutes in total.
The HP argued with me at the start saying I had done an Assessment before for DLA I told the HP it was for ESA they would not back down on this leaving me stressed before the assessment even started, is this normal.
I have amongst other things a hearing disability, the HP kept coming back to this for some reason. On one occasion I could not make out what the HP had said, they had to asked again still I could not hear or understand what they had said to me, the HP eventually had to actually spell the word they were trying to convey to me, even though I had both hearing aids in my ears and they were no more than 3ft from me and talking loudly.
They did not ask me to walk, physical assessment lasted about 2 minutes they did not ask to see my therapy plans, in fact they skipped my home treatments totally along with skimmed over some to the sections, appeared to be in a rush, is this time for an assessment, normal, thanks

Thanks BIS, I filled in my PIP Questionnaire roughly 5500 words of it, plus old Doctors' Report, Plus a nine year old report about my Deafness and Tinnitis from an ENT Consultant, but it all seemed so rushed to me and my wife, who was there the whole time and typed some notes onto a computer, but who knows.

Also forgot to mention, I received a text from the Department for Communities this morning saying they have received the HP's Assessment Report back.
