It's great if that's how you're being scored, but you never know how you're being scored. One interviewer might be happy with a conceptual approach, another one might reject you for leaving off a curly brace.
In my experience some interviewers were not happy that I worked on a brute force solution first, with the aim to optimize it after I got it working. They wanted to see the efficient, optimized solution first. That is counter to everything I read before doing these interviews, and it was, I think, a bit unreasonable.
As much of a cesspool of anonymous gossip as places like Glassdoor might be, reporting this sort of bad behavior might be useful, if to at least force companies that engage in unreasonable behavior to grapple with these poor policies. Or to warn other candidates of what they’re in for.
