In general, I find that assuming that other players will act rationally or in their own best-interests (according to my subjective definitions) is inadvisable. If OP has a major problem with the quality of their hiring process then, by extension, he could also have major problems with his potential co-workers and the organisation's culture.

The value proposition of investing time and effort into interviewing with this company appears to be less than, say, interviewing companies whose priorities are well-aligned with OP from the get-go. That being said, these kinds of "coding puzzle" screeners aren't going anywhere, and may lock him out of great opportunities at great companies.
