Amazon is an exception in the industry as they routinely hire from tier-2 & tier-3 engineering universities. On the contrary, Product Managers come from tier-1 MBAs. My hypothesis is that given Amazon's strong emphasis on engineering processes, they are able to train and uplevel these devs to tier-1 level talent over time.
