First I got a quick screening phone call from oneof the recruiters for about 20 minutes, we talked about my experiences and why would I want to work at Amazon. A few days later I got an email to schedule another phone interview, this time we talked about the same things we did on the first call plus a series of questions like "what would you do if, tell me about a time when you where working under pressure and had meet a deadline, tell me about a time when you take an unpopular decision, tell em about a time when you achieve an objective and what did you do.
After this call I got 2 more phone interviews with the exact same questions and then I got asked to go to the HQ in Luxembourg where I had a full day interview with several people, they all asked the same questions they already asked in the previous interviews so at the end it turned to be a bit boring.
