Amazon Software Engineer interview experience: maximal square and good nodes

Amazon·Software Engineer·Reported Jun 2026

I interviewed for an SDE1 role at Amazon. The early process centered on DSA and, after applying, I went through two technical rounds with different coding challenges.

The first included maximal square and merge intervals, which called for DP or matrix reasoning and careful interval manipulation. In the second, the questions shifted to something like counting good nodes in a binary tree, so I was back to tree traversal and careful counting.

The process stayed focused on those two DSA rounds. I cannot say exactly how it ended from the details I had, but it felt standard for the role: two structured coding evaluations without unrelated detours.
