Amazon Data Engineer Interview Questions

63+ Amazon Data Engineer interview questions drawn from real candidate reports. Sources include 1Point3Acres, Blind, Glassdoor, Reddit, and LeetCode. Questions span every stage of the Amazon Data Engineer loop: OA, phone screen, system design, behavioral, and onsite coding.

What to Expect in the Amazon Data Engineer Interview

The Amazon Data Engineer interview process typically runs 4 to 6 rounds depending on seniority level. Based on candidate reports in the LeakCode database, the loop usually includes a resume review, an online assessment or coding phone screen, one or more technical rounds, a system design round (for senior and above), and a behavioral or values round.

Difficulty skews toward medium and hard LeetCode-style problems in the coding rounds. System design questions test breadth (component selection, scaling, trade-off reasoning) more than deep implementation. Behavioral questions are tied to the company's stated values and principles.

How to Prepare for the Amazon Data Engineer Interview

Use the LeakCode question database as your primary research tool. Filter by role (Data Engineer), then by round type to focus your prep on the specific stages in your upcoming loop. Sort by recency to see what 2026 candidates actually faced.

  • Start with questions from the last 12 months. Interview processes change and recent data is the strongest signal.
  • Cross-reference questions that appear in multiple sources (1p3a, Blind, Glassdoor). Multi-source confirmation means a question has stronger recurrence probability.
  • For system design rounds: focus on the question patterns, not individual questions. The same design principles recur across many prompts.
  • For behavioral rounds: map your experiences to the company's stated values before the interview. Most behavioral questions at top companies are derivatives of a small set of core leadership competencies.
