When I interview candidates, for me the coding interview is an opportunity to see how the candidate reasons about a problem, how they communicate their thoughts and if they are able to ask for help or get pieces of advice and action on them.

Whether they can solve the problem or not it's almost secondary. Of course, there are expectations based on the level for that role, but I prefer to hire someone that fits the team culture rather than some random rockstar developer.

If the candidate can do the exercise correctly and efficiently that's, of course a plus, but again, not a blocker.

Finally, I do think that for more senior roles it is good to also try to have a whiteboard session where you can discuss more high level / architectural problems. This will help to get a full picture on the level of expertise of the candidate and it's another opportunity to have a conversation and see how the candidate explains their idea or react to rapidly evolving scenarios.

I hope this opinion helps, but keep in mind it is only my opinion :)
