Not necessarily "ideal" IMO, but a friend told me about an interview where they told him beforehand "bring your own laptop, set up", then when he arrived they told him "please build this" (I think it was something similar to Everything). After a couple of hours when he was done, they asked him to add some functionality (network support? can't recall).

At least this type of interview seems to solve the problem of developers strangely needing to study for an interview, and I would guess it also better represents coding ability.

Alternate versions can include "debug this" and "design this" (which is pretty popular AFAIK).
