The Amazon interview process for a Principal Enterprise Architect (often referred to as Principal Solutions Architect at AWS) is widely considered to be extremely challenging and complex. This is due to the combination of a rigorous technical evaluation and an intense focus on Amazon's unique culture.

Behavioral Question (LP-focused):

"Tell me about a time you had to make a bold decision with incomplete information." (This maps to the "Bias for Action" LP).

System Design Question:

"Design a globally distributed, highly available e-commerce platform that can handle peak traffic during a major sale event."

Technical Deep Dive Question:

"How would you migrate a large, monolithic on-premises application to a microservices architecture on AWS?"

Architectural Strategy Question:

"How do you measure the business value and ROI of your architectural decisions?"
