The interview exists to test whether the person matches the file. Most applicants pass comfortably; the ones who struggle are those who have never been walked through their own submission.
Know your own numbers
You should be able to explain, without notes, where your wealth came from, roughly when, and how it reached the account funding the application.
Consistency beats polish
Working through this for your own family? Book a consultation and an adviser will assess your position directly.
Small inconsistencies between what you say and what the file shows are what generate follow-up requests. Say you are not sure rather than guessing at a date.
Declare adverse history
Anything a search will find should already be in the file with an explanation. Nothing damages a file faster than an omission the agent discovers independently.
