Case Interviews
Do I have to be perfect in a final-round consulting interview?
I've reached final rounds and I'm worried that the tolerance for small mistakes disappears at that stage. In earlier interviews, people seem to progress despite an arithmetic slip or a missing point in the framework. Is the final round different, or is there still room for ordinary human errors?

I understand the desire to ask this question (peace of mind), but think about how little worrying/thinking about this matters!
Nothing we say will change how you prep/perform...no matter what you're going to (and should) try your best.
The real answer is: You don't have to be better to get in, but even if you are perfect you may not get it!
It depends on office demand, interviewer-candidate dynamic, what types of errors are made, how frequently, etc.
You can "ace the case" and not get in because you just didn't seem like someone they'd want to work with. You can make a couple mistake and get rave reviews because you took in feedback super well, were insightful, and were a pleasure to case.
It honestly depends.
In terms of your specific question though...yes you can make an arithmetic error or two. Yes you can miss a sub-bullet in the structure. Yes (maybe) you can not be especially fluent in fit.
