I got the opportunity to have an interview with Amazon Luxembourg for SDE-1 position.
Sharing my Experience here...

First of all, I would like to tell that I got a referral for the position. Then after clearing the OA, which consists of 3 coding questions ..(I would say hard). I had completed 2 out of 3 questions. After 2- 3 weeks, I got the mail for interview.

As it is quite obvious that Amazon majorly focus on its Leadership Principles. So prepare your stories accrdingly. It will be nice if you prepare it previously, rather than making it on the spot.

I was asked 3 behaviour questions and 1 coding question.

Behaviour Q1 - Tell me abou a time, when you meet tight deadline.
Q2 - Tell me about a time, when you find something that is not going in your way and what I did for the same?
Q3 - Tell me about the time when you heard some negative feedback and what did you do to improve?

Almost 30-35 mins, we spend on discussing the stories. After that we moved to coding part. I was asked only one coding question

Q - Minimum number of platforms required - The ques is same like this, but words are twisted. Have a good discussion on it.

Then I asked few questions to the interviewer and it came to an end.
