Amazon sr Technical Program Manager interview questions

Tell me about a time when you over delivered

The interview was broken down into mostly 2 parts: System Design and Situational questions based on Amazon Leadership principles. 3 interviewers asked me system design questions like: 1. design a database schema for a certain configuration manager 2. Design a service that can handle hundreds of thousand transactions to be executed at a very specific time of the day (think about scale and error conditions) 3. Another question was about a real life problem that the interviewing team was having. I was asked to come up with a viable solution, design the system for the solution and define the APIs for each box (service) in my solution. The other 3 interviewers mostly asked situational questions based on 1 or more Amazon leadership principles. Note, the interviewer will not reveal which leadership principle they are probing on.
