It wasn't an interview, even though they insisted it was. It was a completely automated skill assessment "interview" with an AI. Or put better... it's a CAPTCHA that takes roughly 60mins to complete. If you just happen to pass their CAPTCHA, you might get to then talk to a real person.
I laughed and of course did not continue. This is the biggest honkin piece of baloney I've seen yet. It puts 100% of the burden on the candidates, so the HR department at the company can go back to trimming their hangnails or whatever they do.
