Totally agree with what you say about multiple choice programming tests. I have a PhD in computer science and have worked as a programmer for over a decade. For fun, I took a practice AP CS exam with my son, which had similar multiple choice questions.

I did not get 100%. I actually thought the exam was pretty good, but it tested something like 1% of the skills I use as a working programmer. Skills like API design, software architecture, documenting code, and yes even naming variables, which I think are important to writing quality code.
