When I interview candidates, I state up-front that I care less about the solutions than the steps taken to reach one. It's okay to ask for help or hints when confronted with a previously unfamiliar problem. But if I need to provide too much help, teach the use of basic tools (whether they are logical patterns or universal utilities), and even then getting to A solution requires excessive hand-holding, I will hold that against you.

Also, I will happily invert a question if needed. Showing one way to solve a given problem, I would expect a qualified candidate to be able to point out where it could be done differently.
