Amazon Software Development Engineer II interview questions

Consultant reached out to me, later had 4 rounds of technical interview F2F and all are of medium complexity.

They were pursuing me a lot bcoz their profiles were similar to me. I had worked a lot on Distributed Systems, E-COmmerce, Big Systems. The HR first called up & gave me all the details. I asked about what exactly do they look for in coding interviews. He told me they looked to see basic things like whether the candidate broke down the problem into simple parts & divided the complexity. In the telephonic round the interviewer asked about breadth first traversal.
