I give people the choice of take-home, whiteboard, or code sample. Code sample can be any code they've written for a side-project or even a take-home they've done for another company. Obviously, they can't share actual code they've written for another company, but take-homes are generally fair game... And so that solves the O(N) problem for people who are applying to multiple companies.
