I find this highly unlikely. My first day at Amazon I encountered an engineer puzzling over a perfect sine wave in a graph. After looking at the scale I made the comment "oh. you're using 5 minute metrics." Their response was "how could you figure that out just by looking at the graph?" When I replied "Queuing theory and control theory," their response was "what's that?"

Since then, Amazon's hiring practices have only gotten worse. Can you invert a tree? Can you respond "tree" or "hash map" when you're asked what is the best data structure for a specific situation? Can you solve a riddle or code an ill-explained l33tcode problem? Are you sure you can parse HTML with regexes? You're Amazon material.

Did you pay attention to the lecture about formal proofs. TLA+ or Coq/Kami? That's great, but it won't help you get a job at Amazon.

The idea that formal proofs are used anywhere but the most obscure corners of AWS is laughable.

Although... it is a nice paper. Props to Amazon for supporting Ph.D.'s doing pure research that will never impact AWS' systems or processes.

Cool anecdote but I'm not sure how reasonable it is to expect every person to have expert domain knowledge and recall of every single computer science field just because they got a job to work at Amazon or any other MAANG company.
