Can visa officers check for this detail themselves and I just simply acknowledge that I'd been refused a visa before and why, or should I be really honest and tell them the details as well (when, where, how many, etc.)?
What's the best way to go about it?
EDIT: I probably should clarify, but I don't mean visa interviews. I was more specifically referring to the application forms that usually has one question asking whether you'd previously been refused any visas before where they provide a space for you to explain.
