Preparing for a coding role at Amazon demands more than just solving problems—you need speed, clarity of thought, pattern recognition, and the right training materials. If you’re looking for the 5 best resources to prepare for Amazon coding interview loops, this guide gives you curated options, how to use each one effectively, and a suggested prep plan.
Whether you’re prepping for the online assessment, phone screens, or the on‑site loop, these resources will help you build structure around your study.
1. Grokking the Coding Interview Patterns for Coding Questions
This resource breaks down coding interview problems into repeatable patterns, sliding window, two pointers, graph BFS/DFS, dynamic programming, and helps you internalize the building blocks of Amazon interview questions.
How to use it:
- Work through each pattern module carefully.
- After completing one, tackle fresh problems that employ that pattern.
- Time yourself and review your solution for clarity, edge case coverage, and efficiency.
Why it stands out: Amazon interview loops reward pattern fluency and fast identification of the right approach.
2. Amazon Coding Interview Guide
This guide is tailored to Amazon’s interview style: online assessment, phone screen, and full loop. It breaks down topic frequencies, typical question types, and example problems.
How to use it:
- Read the “What to expect” sections to align your mental model of Amazon’s process.
- Map your gap areas using the guide’s frequency data.
- Use the sample problems to test yourself under timed conditions.
Why it stands out: This guide helps you focus on Amazon’s norms rather than generic coding prep.
3. Grokking the Coding Interview Patterns by dipjul
An open‑source repository that aligns with the pattern approach but adds community‑driven practice problems, solutions, and commentary.
How to use it:
- Pick one pattern you’re weak at and solve at least one problem without hints.
- Compare your solution to those in the repo; annotate where your approach differed.
- Track recurring mistakes and revisit those patterns weekly.
Why it stands out: Reinforces pattern‑based learning with practical self‑assessment and community feedback.
4. AlgoExpert Coding Interview Course
AlgoExpert offers curated coding problems, step‑by‑step video explanations, and timed practice aligned with Amazon’s difficulty range.
How to use it:
- Start with core data structure modules.
- Solve ten to fifteen medium and hard problems to match Amazon’s expectations.
- Watch solutions after attempting problems under realistic timing.
Why it stands out: High‑quality videos and polished explanations make it ideal for structured, self‑paced learning.
5. LeetCode Premium Coding Interview Prep
LeetCode Premium remains one of the most widely used platforms for Amazon interview preparation. Although not company‑specific, it offers a dedicated collection of Amazon‑tagged problems curated from real candidate experiences. These cover the difficulty, style, and breadth Amazon expects across its online assessment and interview loops.
How to use it:
- Start with the Amazon-tagged problem list to target high-frequency topics.
- Solve problems in sets of two to simulate Amazon’s online assessment pacing.
- After each session, review your time complexity, edge cases, and communication strategy.
- Revisit patterns you struggled with and connect them back to Resources 1–3 for reinforcement.
Why it stands out: It provides the closest real-world problem distribution for Amazon interviews and helps you benchmark your performance against thousands of other candidates.
How to stitch them into a prep plan them into a prep plan
Here is a six‑week schedule you can follow:
| Week | Focus |
| Week one | Complete four pattern modules from Resource 1; map topic gaps using Resource 2. |
| Week two | Solve ten to fifteen fresh problems; use Resource 3 to compare solutions and reflect on mistakes. |
| Week three | Begin Resource 4; complete timed drills and focus on Amazon-style medium and hard problems. |
| Week four | Use Resource 5 to work through Amazon-tagged problems; simulate two assessment-style sessions. |
| Week five | Perform two full mock online assessments; conduct a detailed post-mortem using Resource 2 and correlations with Resource 3. |
| Week six | Final polishing: complete three timed practice blocks using Resource 5, refine weak patterns using Resources 1–3, and prepare interview mindset. |
Final tips
- Clarify requirements first: Amazon interviewers expect clear problem scoping.
- Communicate your thought process: structure your explanation clearly.
- Write clean, testable code: simplicity wins under time pressure.
- Emphasize pattern recognition: fast pattern detection gives you more time to optimize.
- Treat each mock and review session as data to refine your thinking.
With these five resources in your toolkit and a clear study plan, you’ll be well‑equipped to take on the Amazon coding interview challenge.
Happy learning!
