Interviewed for silicon team. Have only been asked about the domain specific knowledge in 1st round and system design in 2nd round and C coding in 3rd round.
The interviews were 50 mins each.
J'ai postulé via une autre source. Le processus a pris 2 jours. J'ai passé un entretien chez Amazon en sept. 2011
Entretien
Amazon contacted me when I updated my resume on Monster. After a call from their recruiter, I was asked for a first technical phone interview. I did not do well in that interview, however I got asked to do a second technical interview in which you are asked programming questions I think I did better but I did not get the job.

Question 1
Define the strategy pattern and when could it be used
How would you implement a priority queue. What is the O analysis of your implementation. How would you store a tree structure. How would you implement a tinyURL service.
given a tree write a function isSymmetrical that would find out if the tree is symmetric or not.
-----
Class Node
{
Node leftChild
Node rightChild;
int value;
}
//Write this method:
boolean isSymmetrical(Node treeRoot) {
Examples:
This is symmetrical
7

5 5

9 9

2 8 8 2
This is not symmetrical (value difference):

First round with hr screening - 2 leetcode questions then hr manager screening then the loop which consists of 4 interviews each an hour long. The 4 interview questions they asked where three medium leetcode questions. And one system design interview question about how to shadow deploy a test software to millions of users.
Recruiter reaches out after applying through Amazon careers, no referral. Had an initial OA, then after a month had four rounds in two days - three coding one system design. Each round had 30 min behavioral and 30 min coding.
