You're right that doctors have a well-established credentialing process, but yes, I believe that they are asked questions like that. Or maybe "For a herniated bupkis, some doctors prefer the Bloggs reduction, while others prefer the Quimby resection. Which do you prefer and why?"
There are nearly as many poseurs in mechanics as there are in programming, though. I think reputable shops grill candidates pretty hard. And not with Fermi questions.
I guess the only doctors I've known are ones going through the state run education and health system and it seems pretty streamlined. You go and work where you're told to based on your educational choices and achievements, there aren't interviews as such. It must be different going into a private health system.
