@martinskypemartin, I agree with
@Sm1smom, most of those who have had the interview have documented their interview experience in this thread. It's just a matter of looking for them.
And re the documents, it's important - from those who have gone to interview - to just give them what they ask for on the checklist. Nothing more. When they check the documents, they only want to see what is on the checklist.
Having said that, while I have four near piles of documents and the checklist on each, I have another file with ancillary information like degrees, financial information, CVs etc. If they don't ask, that file doesn't get used. But if they do ask, I have the documents ready for them to see, complete with copies.
