The ESA Claim guides explain about the assessment and have a list of the questions you are likely to be asked.
Unless you have problems with communicating verbally, I would expect the assessor to direct their question to you and may object if anybody with tries to answer on your behalf.
However, if you have missed anything important then your companion should feel free to remind you about it.
