The issue is not not being able to write binary-search; but, given a set of constraints, a very well defined set of steps, and ample enough time; is the candidate able to write it in code what's there in their head (a pretty straight forward algorithm).

I expect candidates to write in code what they can explain verbally, given that the code is do-able in the confines of an interview.

That said, I also get what you're trying to say: Capably implementing Binary Search may not be the best indicator of skill, since Software Engineering is so much more than just converting thought to code.

Right. There are two ways you get to implementing binary search in an interview: (1) figuring it out from some basics & possibly hints or (2) reciting it from memory. 1 is useful, 2 is useless. Having used inteviewing.io, it facilitates #1 much more than #2, as a good process should. Interviewer ratings help that.
