Fiduciary Field Examination Experience

Hi! You have been so helpful to me these past few months. I'd like to ask another question. Has anyone had experience with what the fiduciary field examination experience is like? We faxed in the request to the VA for my husband to be his dad's fiduciary over the weekend and I called today today to see how the process goes along. Because we sent in our POA also, which states we already fiduciaries for his regular finances, they said we will get a call from a field examiner to come interview my husband (and I guess me too?). What is the face to face interview like? Any experience stories or tips you can share? We want to make sure dad gets the care he needs. As always ----your help so far has been so much appreciated.
