Sure.

>>And doing that out loud is the one of the few ways people can see how/if you do that.

Strongly disagree. I would posit that written explanations are a much better indicator of someone's ability to reason about problems, because:

a) They can provide hyperlinks, images and other supporting materials to aid their explanation

b) You also get to see if they are a competent writer, which is also a very important skill for an engineer
