Missing info you base a claim on elsewhere anywhere in your app/resume is certainly not going to help. But yeah, it ought to be readable and internally consistent and something a reviewer isn't going to have to take time to puzzle over far less catch you in some glaring error.

But what I thought was key is that they give you interview directions and they expect you to have put in the work to be able to follow them. I wouldn't bet a career on 'close enough for government work. When they give you the questions and answers ahead of time they expect you to have them.
