We’re a company that brings a wide range of perspectives to inventing on behalf of our customers. A significant portion of the conversation will focus on how you’ve demonstrated our Leadership Principles in your past jobs. Instead, we’ll focus on the ‘what’ and ‘how’ of your experiences, as well as the ‘why’ of your decisions. Expect to be asked to write syntactically correct code—no pseudo code.

We’re here to help you navigate through the chaos and master those specific features that will make you shine in an AWS system design interview. So, let’s dive in and explore these features within the broader context of cloud computing architectures, scalability strategies, and system reliability. The second online assessment (OA2), is a set of two data structure and algorithm questions. Each question needs to be solved within a certain amount of time (e.g. 30mins).
The process
You should practice a lot for coding and design interviews and get to experience a practice interview before the real thing. The mock interview will help level up your skills and calm your nerves. I recommend you to use our peer-to-peer mock interviews platform for LeetCode and System design preparation. With proper preparation and some practice, system design interviews can be much easier than people expect.
How to Nail your next Technical Interview
It's also important to note that recruiters and people who refer you have little influence on the overall process. They can help you get an interview at the beginning, but that's about it. The first online assessment (OA1), is a set of seven debugging questions you have to work through in 20mins. Designing a large-scale system will always involve trade-offs and constraints. When presented with a system design question, be sure to identify these constraints and consider the trade-offs involved in different approaches. By considering these factors and making the appropriate design choices, you can create a highly engaging and reliable social media platform.

Finally, a great way to practice coding, system design, and behavioral questions, is to interview yourself out loud. This may sound strange, but it will significantly improve the way you communicate your answers during an interview. Well-preparation is a ‘must’ if you want to crack the system design interview and land a job offer in this top tech company.
Otherwise, without good preparation, system design interviews are tough to crack. System availability and reliability are important factors to consider. Designing for availability and reliability requires an understanding of fault tolerance, redundancy, load balancing, and failover mechanisms.
APIs are kind of like the bridges that connect the roads of major software products. As a result, they are a central part of the system design of major apps like Instagram, YouTube, Twitter, etc. URL shortening services like TinyURL, Bitly, etc. provide short link aliases that redirect to longer URLs. Here are some points of consideration to help you work out how to build this kind of system. Some of the above considerations were inspired by this in-depth solution to the question, so feel free to check out that resource. Let’s walk through an example of how you could approach the problem if you were asked to design a chess game.

Amazon System Design Interview Questions
Your online shopping system will need to store an inventory of products with lots of categories, allowing customers to search through them and make purchases. You'll also need to think about how you handle the expanding load on the website and prevent it from crashing on key retail days. Real-time messaging apps are a common standalone product, or a built-in feature of larger systems. For this question, you might be asked to design a specific app, like WhatsApp or Facebook Messenger. Talking about strategies for upgrading/downgrading systems without major disruptions (near-zero downtime) shows off your technical expertise and strategic thinking. Sharing real-world scenarios where you’ve used AWS’ elasticity capabilities is solid proof of your skills.
This exceptional deal on IT training provides you access to high-quality IT education at the lowest monthly subscription rate in the market. Boost your IT skills and join our journey towards a smarter tomorrow. It’s also a test of your communication and strategic thinking abilities. Being able to upgrade or downgrade with near-zero downtime is a valuable skill that impresses employers. Think strategically about how different technologies fit into larger systems architecture contexts. To ace it, use a repeatable answer framework that tackles different aspects of the problem at hand.
System design interview tests the ability to analyze problems and create a system that can solve a company’s or client’s problems. This interview measures your effectiveness and efficiency for solving a complex specific problem conveniently. Each interviewer will typically ask two or three behavioral-based questions about successes or challenges and how you handled them using our Leadership Principles. These areas include both technical competencies and non-technical competencies that are based off of our Leadership Principles, which different interviewers will be assigned to evaluate.
To finalize your design, play to your strengths by choosing a component you’re more familiar with and drilling down on it. If you’re not sure which component would be best to explore, ask your interviewer. Call out any assumptions you’re making that will influence your design approach. If applicable, ask about non-functional requirements such as availability, consistency, scalability, etc. We’d encourage you to begin by studying these topics, and once you understand the basics, you can begin practicing system design questions.
Now that we've explored some key system design concepts and common interview questions, let's delve into some tips for answering those questions effectively. Three or four of your interviews will include coding questions (i.e. data structure and algorithm questions) which you'll need to solve on a whiteboard. For the technical part of the interview, you can expect typical data structure and algorithm questions which you'll have to solve in an online collaborative text editor such as collabedit. The editor won't have syntax highlighting or autocomplete features which you'll need to get used to during your interview preparation. System design is mandatory to prepare for interviews for all experienced candidates, with 2+ years of experience.
It is okay to change some components at this stage if you think it will improve the system, but you must explain to the interviewer what you are doing and why. The questions below are organized by company, to help you find the most relevant ones for your interviews. For a full answer to this question, take a look at the video guide below by Naren from Tech Dummies. You'll need to design a system that can scale to millions of users and handle petabytes of data.
Here are some points you must consider the following points to ace your final representation.
For example, if you're designing a search engine, you might need to consider the trade-off between search speed and search accuracy. You might also need to consider constraints such as the amount of available storage and the number of queries that the system needs to handle. By considering these factors and making the appropriate design choices, you can create a highly efficient and reliable web crawler. Consider any bottlenecks that may arise when it comes to the system’s scalability, performance, or flexibility.
