How Difficult is Amazon SDE Interview? (an Overview)

As you hover your cursor over the ‘Apply’ button for the Amazon SDE role, a whirlwind of thoughts might cloud your mind. Questions about the difficulty of the interview, the competition, and whether your preparation is adequate enough, start to create a symphony of doubts and what-ifs. Let’s face it, stepping into the arena of one of the most sought-after tech positions can feel like gearing up for an intellectual marathon with hurdles at every mile.

But here’s a silver lining – this blog aims to shed light the Amazon SDE interview process for you. By providing an honest, no-frills overview of what to expect, including the types of questions, the interview format, and essential preparation tips, we hope to turn your anxiety into anticipation.

Quick Takeaways:

  • Master the STAR method for behavioral questions to structure your answers, emphasizing situations, actions taken, and results achieved.
  • Delve into concurrency and multithreading problems, as expertise in these areas can differentiate you in technical interviews.
  • Integrate Amazon’s Leadership Principles in your responses to showcase alignment with the company culture and decision-making process.

What Exactly Is the Amazon SDE Interview Process?

Diving into the Amazon Software Development Engineer (SDE) interview process, it’s a journey that tests not just your coding mettle but also how you approach problems and work within teams. Initially, you might face an online assessment (OA) composed of coding challenges and work simulation exercises designed to evaluate your problem-solving skills in a virtual work scenario. If you navigate through this successfully, you’re likely to be invited for phone screens, and eventually, the onsite interviews, which are the real deal.

The onsite rounds are where things get more intense. You’ll be put through a series of interviews – usually four to six – that assess your coding abilities, design insights, and behavioral traits. Each round is meticulously structured to gauge different facets of your skill set. And it’s worth mentioning, every interaction, every problem solved, feeds into Amazon’s holistic view of your capabilities.

How Technical Can the Questions Get?

When it comes to the technical depth of Amazon SDE interviews, buckle up. You’re not just solving riddles; you’re demonstrating real-world problem-solving skills. The coding questions can range from data structures and algorithms to system design, depending on the role and level you’re applying for. It’s not uncommon to encounter problems that require a strong grasp of binary trees, dynamic programming, or graph algorithms.

Here’s a unique tip most folks might overlook: delve into concurrency and multithreading problems. With the shift towards more distributed systems, showcasing your skill in handling concurrent operations can truly set you apart. For example, brushing up on Java’s concurrency utilities or understanding Python’s Global Interpreter Lock (GIL) can make a noticeable difference in your responses.

What About the Leadership Principles?

Amazon’s Leadership Principles aren’t just HR fluff; they are the spine of the company’s culture and decision-making process. Each candidate must demonstrate their alignment with these principles, through both direct questioning and behavioral examples. But here’s the kicker: integrating these principles into your technical responses can provide a significant edge.

For instance, when discussing your approach to solving a technical problem, weave in principles like “Bias for Action” or “Insist on the Highest Standards.” If you led a project that required a quick turnaround, frame your narrative around “Bias for Action” to highlight not just your technical acumen but your decisiveness and leadership qualities.

Stressing on “Customer Obsession” can also pay dividends, especially when you discuss designing systems or features. Showing how you’ve prioritized user experience or solved customer pain points demonstrates a deep understanding of why you’re building what you’re building, not just how.

In summary, the Amazon SDE interview can indeed be a challenging mountain to climb. However, understanding the structure of the process, diving deep into technical preparations, and aligning your experiences with Amazon’s Leadership Principles can equip you well for the journey ahead. Stay curious, practice diligently, and remember, each step of this process is designed to unearth not just a competent engineer, but a well-rounded Amazonian.

Can You Prepare for the Behavioral Questions?

Absolutely, and here’s the kicker: mastering the behavioral questions can give you a significant edge in the Amazon SDE interview process. Amazon places a huge emphasis on its leadership principles, and your ability to demonstrate these in your answers is crucial. Let’s dive into how you can ace this section.

Embrace the STAR Method

S ituation, Task, Action, Result – the STAR method is your best friend here. It provides a structured way to answer behavioral questions, ensuring you hit all the key notes without wandering off into irrelevant details.

  • Situation: Set the scene. What was the context of the situation you were in?
  • Task: What was required of you?
  • Action: What steps did you take to meet the requirement?
  • Result: End with the outcome. How did your actions impact the situation?

For instance, if asked about a time you handled a deadline under pressure, outline the project’s context (Situation), your specific role (Task), the strategies you employed (Action), and the successful submission or outcome of the project (Result).

Practice, But Don’t Over-Rehearse

You want to come across as genuine and spontaneous, not like you’re reciting a script. Prepare your examples, but let the conversation flow naturally. Adjust your examples to more closely align with the interviewer’s questions if needed.

Unique Tip: Reflect on Failures as well as Successes

Here’s something not everyone will tell you: Amazon values the ability to learn from failure. Prepare an example of a time things didn’t go according to plan, what you learned, and how you applied that lesson moving forward. This can set you apart as a reflective and resilient candidate.

What Are Common Pitfalls to Avoid?

Navigating an Amazon SDE interview is akin to running a marathon with hurdles; it’s not just about speed but also about how well you can avoid stumbling. Let’s highlight some common pitfalls and how to leap over them gracefully.

Not Knowing Enough About Amazon

It sounds simple, but you’d be surprised how many people walk into the interview room without a solid grasp of Amazon’s products, services, and especially its Leadership Principles. Make sure you’ve done your homework.

Skipping the Basics

In the heat of preparing for complex algorithm questions, don’t forget the basic coding principles and data structures. Brushing up on these foundational elements can save you from tripping up on simpler questions.

Underestimating the Behavioral Section

Many technical candidates breeze through the coding challenges but get snagged on the behavioral questions. Remember, Amazon is as much about culture fit as it is about technical chops. Prioritize preparing for this section as much as you do for the coding part.

Ignoring the Feedback Loop

After each practice or mock interview, take a moment to reflect:

  • What went well?
  • What could have gone better?
  • How can I improve for next time?

Incorporating this feedback loop into your preparation can significantly improve your performance.

The Laundry List Effect

When asked about their experience or approach to a problem, some candidates reel off a list of technologies or methodologies they’ve worked with, without delving into specifics. Instead of listing every buzzword you know, focus on detailing one or two relevant examples clearly and thoroughly.


Navigating the Amazon SDE interview successfully boils down to thorough preparation, self-awareness, and the ability to communicate effectively. By understanding and preparing for the technical and behavioral components and sidestepping common mistakes, you set the stage for a compelling performance. Remember, it’s not just about proving you can solve problems, but also about showing you fit within the Amazon ethos. Good luck!
