I had my PIP Interview and the guy doing it was a Physiotherapist who had no clue about mental health issues at all.
Although I can physically do a lot of the assessment criteria but I need support, encouragement and/or reminding to do some of those things and he just basically wrote those things off because I am physically capable of doing so.
I was reduced to tears halfway through the interview and the guy just carried on with his domineering and aggressive approach over me.
