Good point! We do our best not to test any skills that would be tested in a CAD certification.
Our questions and rubric don’t emphasize style for eg or comfort in a software. The collaborative CAD portion is a section where more complex engineering questions are answered, through a platform and in a way where they’re usually solved in the workplace. We view this as analogous to the coding portion of a software engineering interview.
You should show an interview example with engineering questions then. The questions in your example interview are technician-level. Checking a mechanical drawing for consistency is not an engineering task - the job that does that is "design checker". Design checkers typically have associate's degrees in drafting or CAD operation. The DFM question is arguably engineering but it could be even better answered by a machinist.
Engineering questions do not have to be complex, but they are different in kind.
