Maybe. All other things being equal, they might need a reason to cut you, and hire the other guy. If you failed to complete the problem or took longer than expected to complete it because of extra complexity entailed by a more "correct", out-of-scope solution, it may especially cost you - even if in the end, your solution was "smarter". Maybe the other guy noted that there are a couple of ways to solve the problem, and asked a clarifying question about it.
