I've taken an aptitude test for my first job and did really well. I just took more than an hour, but it kicked off my IT journey, so I'm not too mad about tests. But it was more for a practical exam, rather than one of those definition and memorization exams, with questions like "What are the pillars of OO Programming?" I'm so much better at figuring things out on the fly vs memorizing what syntax is.
Same here. So that's the thing. In my industry an equivalent question would be: "What is the best way to structure a campaign hierarchy?" It's some primary school bullshyt that no self-respecting campaign manager for any channel (SEM,E-mail,Display,Social, etc.) follows to a T. Asking a dude who worked on major fortune 500 clients campaigns for 3+ years or more this question is frankly insulting, and similar to your situation (unless you are entry level) it sounds insulting to your intelligence. There are a trillion different ways it can be organized based on the brand's goals, reporting needs, analytics and testing methods. It's not solely based on key performance indicators (KPIs) like CTR, CVR etc.
A better question is : "What is the appropriate optimization when your CTR is ____, CPC is _____, conversions are ____ etc." There's no right or wrong answer per se. There are like 5 different ways you can approach it or more. The wrong answer is not understanding what the implications are of the situation. As long as you explain those implications correctly you should "pass" regardless of the solution you provide.
I am a get it done type of guy and if I can't get it done in the typical way I find creative ways to get around the roadblock and use a workaround solution in the interim. I don't follow things by the book.
