I applied through an employee referral. The process took 3 weeks. I interviewed at Amazon
Interview
3 phone / skype interviews.
the first was with HR. She asked to review the code and explain few things about the given code. The second was with a technical guy, he gave 3 questions. All questions were quite familiar from the Cracking Coding Interview book. The third interview was about the system design. The question was "how would you implement the ITunes". Here I was quite weak. The next day after the third interview I got a decline.
Interview questions [3]
Question 1
given a method
private LinkedList doAction(List l1, List l2) {
LinkedList ret = new LinkedList();
for (int i = 0; i < l1.size(); i++) {
for (int j = 0; j < l2.size(); j++) {
if (l1.get(i) == (l2.get(j))) {
if (!ret.contains(l1.get(i))) {
ret.add(l1.get(i));
}
}
}
}
return ret;
}
questions:
* what does the method do
* what is bigO for the method
* how to improve the method
* how to test the method
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.
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.
