Amazon Software Development Engineer SDE interview questions

3 rounds: 1st round: intro, bq, and ood 2nd round: bq many follow up 3rd round: intro, bq, and coding questions: 1. conflict 2. dive deep 3. challenge 4. mistake

It started in January and ended around May, so pretty long. It had a recruiter screen, online assessment and a loop. Interviewers were friendly and helpful throughout the loop. For lc, I prepared using amazon tagged questions, and for lp questions they asked follow up questions, but they were not probing, mostly curious.
