Very much yes. In an interview I was prompted to write some code that ran as quickly as possible. 10 minutes in they were concerned that I hadn't started with a naive proof-of-concept solution and improved from there. I don't disagree with their idea of good programming practice, but how could I know they wouldn't penalize me for coming up with a slow naive solution, when the prompt specifically said to run as quickly as possible?
