Amazon Software Development Engineer (SDE) Intern interview questions

There was only one round of tech, in which they asked me two questions, one from DP on a grid, and another from sliding window on arrays. Having completed that, they asked me about Trie, but didn't really ask a question about Trie.

A basic online assessment with very easy questions lead to a 30 minute zoom interview with generic algorithms questions. After that, an offer came within a week. Very generic pipeline, no direct point of contact.
