I know a couple people at Audible and was referred there for a Technical Program Manager position.
Passed a couple of phone screens which were straight behavioral interviews then was scheduled for in-person.
I was asked to submit an essay picking from one of two essay questions, emailing my response at least 24 hours before the scheduled in-person session.
Two essay choices were:
a) Tell us about when you had to make a decision when not all the inputs were known. What was the background, what was your though process and reasoning, what decision did you come up with and what was the outcome
b) Tell us about something you did that was innovative, similar to (a), give the background, process, results
I wrote an essay about innovation.
For the in-person I ended up meeting with 6 people + HR. These were behavioral interviews with a twist -- each of the 6 interviewers were following a theme:
First had all questions about 'Customer Focus'
Another had questions about 'Maintaining High Standards'
Another had questions about 'Building and maintaining Trust' etc
all tie back to Amazon Leadership Principals.
There was one interviewer who was responsible for grilling me on the essay I wrote.
All the interviewers were tough and grilled hard but were also generally fair. The interviewer asking me about my essay clearly did not like the example of innovation I gave in the essay and seemed predisposed to negative outcome.
About a week after the in person interview I heard back from my friend who originally referred me -- no offer. The interviewing panel was split decision on whether to pursue me and as per their policy they have a preference to turn down a potential good hire to avoid a potential bad hire. They were on the fence with me and opted not to continue.
