Amazon Software Development Engineer interview questions

Applied on the website and got call from a recruiting coordinator. She setup the interview a week later. It was a phone interview and I was asked a question on linked list. We came up with two different solution and then, I was asked to code the one with best time complexity. Heard response in 2 days and moved on to 2nd round. I was asked a design question on which I did not do well.

I am from Madrid, Spain and the position was for Seattle, WA. I contacted a recruiter via email. The whole process took 3 months. They sent me a link to do an online test, through interviewzen. It consisted in two parts: - Java coding. It was about binary trees and recursion. - OOP question. It was about inheritance and polymorphism. I passed the test so they scheduled a technical phone interview with an engineer few weeks later. This was the script: 1) Questions: - First question apart of “Is this a good moment?”: Why do you want to work here? => You better be ready for this. - Which projects of your career are you proud of? - Which languages are you familiar with? - Why? => I didn’t expect this question. - Are you familiar with trees? - Really? What is a tree? 2) Technical part, coding. - We used collabedit. - It was about binary trees and recursion again. - It’s not worth it to put the question itself, just be ready to be asked about data structures, recursion and efficiency in terms of Big O. 3) Interviewing the interviewer. - You should have 3-5 questions for them. It took one hour and one minute. They sent an email 3 days later saying "we have decided to move forward with the search process in order to target the candidate…”. Looking backwards I don’t think it was difficult. I wasn’t ready enough. They were very kind with me all the time and I learnt a lot during the process.
