We had two rounds for Catalog associate role, first one was aptitude, I guess we had around 50 questions and some time allotted to answer (I do not remember well) These questions included logical, maths, English grammatical and one more set. Few of us were selected from the first round 2nd round was face to face interview, where I had to interviewers, luckily really sweet. They asked me general questions like, Tell me about yourself, Why do you want to work at Amazon, Tell me what do you know about this role and why should we hire you, They tested my English asked me to write really small essay about my fav topic, tell me about your project (Project was in my CV), asked me why did I score less overall percentage in my graduation :P
