Amazon SDE Interview Experience 2026

Interview Overview

I recently completed a software engineering interview process.

The process included three rounds.

Round 1: Coding

The first question was an array problem.

My Approach

I used a hash map to reduce the lookup time.

def solve(nums, target):
    seen = {}

    for i, num in enumerate(nums):
        need = target - num

        if need in seen:
            return [seen[need], i]

        seen[num] = i

Complexity

What I Learned

1. Explain your approach first.
2. Clarify edge cases.
3. Analyze complexity.
4. Keep communication clear.

Writing correct code is only one part of the interview.
