There is a selection bias here as others have noted, the exam is likely biased in favor of younger, unmarried workers, especially those without children who have 2-8+ hours to spend on top of their other commitments.

I applaud their decision to pay for correct answers, as it balances the "cost" bourne by the applicant and employer. Employers who send out tests en masse have an asymmetric advantage -- they can force many candidates to incur a cost without incurring much or any cost of their side. This causes bad behaviours.

Traditionally in interviews, companies "paid" with their time, but online exams skewed that. Paying something per correct answer at least makes them think twice before inviting hundreds to the exam that they have no real intention of ever interviewing.

To be fair, younger workers will usually have less of a professional network; older workers will usually have more of a network, and are more likely to have open source code that's reviewable.

It's all just ways to filter. If I can filter you through our mutual network, I'll do that - if I can't, open source code; if I can't, coding test.
