I'm under an NDA, so I can't provide any questions. However, do standard technical interview prep and really understand Amazon's culture and leadership principles, they will come up and they are important (you can fail interviews even if you are likable and do well technically if you don't have good answers here).
The first round was an online interview. The question is as follows, All the leaves in a BST are removed iteration by iteration until the BST becomes empty. These leaves are stored in an array and are given as input. We are supposted to give the preorder travesal the Original BST. The input some what looked as follows, { B, D, H, P, Y, C, M, G, Q, K } Simpler solution would be to just constuct BST by supplying the inputs in reverse that is from K to B. And then do a preorder traversal. But I tried to do this with out constructing the BST and wasted a lots of time and hene failed.
