I think finance will hang me upside down if I even mention that we need to provision virtual cards for every candidate
I think “we offer a $50 (or $20 or whatever) Visa/Amex gift card as part of this interview step” is easier to admin, might skate by finance more easily, and avoids all the tech support angles of “here’s how to use our specific tooling” and concerns of them misusing your key for something nefarious.
