Process
Was contacted by a recruiter.
Had an initial screen with the recruiter to discuss background and interests. This was followed by an initial coding screening using CoderPad, which I failed.
The question asked was unusually difficult for an initial screening. It seemed like you either had an "aha" moment and got it, or you failed.
It also didn't seem to relate to the kind of work the team actually did. The team focuses on core infrastructure work, but the question asked to invent a novel algorithm on the spot under interview pressure.
Questions
Design and code an algorithm to randomly generate mazes for a children's book.
