Hi Diane
You need to ask them to record the call, and if you're able to, we always suggest that people do their own recording.
I would also look at the Guide to PIP claims and reviews. You will find information on what types of questions you could be asked at interview - page 128 onwards.
benefitsandwork.co.uk/guides-for-claimants/pip Don't let them hurry you. If you can't answer a question - don't guess at it - just say you don't know or can't think. You've already had a bad experience - so you know that not all assessors are empathetic. I really hope that it goes well this time.
