A good WBI should feel like a discussion with a peer. While I think the interviewer has to be careful not to direct/guide things too much, they should be giving input/feedback/questions along the way, much like a coworker on a real design problem might. Dumping pseudocode shouldn't ever be the metric to evaluate a WBI, but just a product of the conversation with the interviewer, which is a far more interesting indicator.
