"Do you Require Assistance in an Interview?"

When it comes to interviews, I believe that I require assistance but I don't really know the options as to who can assist me in my interviews, and what it's even like to have someone assist you in an interview. My mum has said she would be willing to assist me, but I don't know how long she'd be up to it for? I probably will be fine to do interviews on my own in the future but for now, I don't know.

I also want to ask anyone that has previously had or currently has assistance in interviews; what it is like?
