Breaking down the System Design Interview: 20 things engineers want to know by Fahim ul Haq
Table Of Content
Being well-prepared for a system design interview can make a significant difference in your chances of landing a job at a top software company. This is where Grokking the System Design Interview comes into play, offering a comprehensive course that prepares you for this essential stage of the interview process. In addition to online platforms, reading books can provide valuable insights into system design. "Designing Data-Intensive Applications" by Martin Kleppmann is a comprehensive guide that covers various aspects of designing data-intensive systems. It explores topics like data modeling, distributed systems, and fault tolerance, offering practical advice and real-world examples.
Evaluating Your Performance
Crossing this gap between engineering levels can take a long time and it’s not something worth rushing. After you are intimately familiar with what your team is working on and comfortable with the example talking points above, start paying attention to some crucial soft skills. This is one of the biggest discrepancies between a very technically skilled senior engineer and a staff engineer. Over 15+ years, I designed large-scale distributed systems and conducted hundreds of System Design Interviews. For the social media feed system, you can study how platforms like Facebook or Instagram handle the large volume of user-generated content and deliver personalized feeds.
System Design Topics and Concepts You will learn in this course
Outlining a sustainable architecture that meets the initial requirements shouldn’t really require you to discuss microservice-level scalability. By approaching the conversation with RESHADED, you can be sure that you’re on the right track. It can be overwhelming to tackle such a complex topic in such a short amount of time. Practice outlining distributed systems using the aspects of System Design in this format so that it is second nature when you actually sit down with an interviewer.

The course was well structured, detailed, and discussed popular System design questions with in-depth analysis and their use of diagram was amazing. System design has always been a core focus for Educative’s team – that’s because our co-founders helped build pioneering distributed systems at companies like Microsoft and Facebook. Recently, large companies have also put forth system design questions to some junior candidates.
Conclusion: Is Grokking the System Design Interview Worth It?
Also what your level is but these are some of the more frequent interview questions. Learning system design can give you a competitive edge in the job market, and it can also have a significant impact on your earning potential. Engineers with system design experience are in high demand, with the difference in compensation between an E4 at Facebook and an E5 being, on average, $121,000[1]. As its name implies, Grokking the Modern System Design for Software Engineers & Managers is for anyone looking to advance their software engineering career.

We can tell the interviewer that there are many other things that a real WhatsApp does that we don’t intend to include in our design. If the interviewer has any objections, we can change our plan of action accordingly. We figure out the requirements and map them on to the computational components and the high-level communication protocols that connect these subsystems. Our system design course is equally useful for people already working and those preparing for interviews.
Identify any areas where you struggled and consider how you can improve your understanding and approach in future interviews. When examining the ride-sharing service case study, you can learn from companies like Uber or Lyft, which have built highly scalable and reliable platforms. Analyze how they handle ride requests, driver matching, and real-time updates to provide a seamless user experience. When proposing a high-level design, consider the various technologies and architectural patterns that can be used. For instance, in the ride-sharing service, you might consider using a microservices architecture to decouple different functionalities like user management, ride matching, and payment processing. System design is all about making decisions and weighing the pros and cons of different options.
This course is designed to prepare you for the real world, and as such, it concludes with a section on spectacular failures where small mistakes brought down large, successful applications. It’s commonly believed in the systems community that when some aspect of the system increases by a factor of ten or more, the same design might not hold and might require change. Not only that with the help of this guide, but I was also able to get more job offers from IT companies. Reading press releases and engineering blogs can be tough to make a habit of, but we have you covered with this newsletter.
Only one in five candidates pass the entire technical interview process at top tech companies after they make it past the screen. It’s important to know this interview because it’s become vital for landing a job and establishing the trajectory of your career. As I’ve written before, the SDI determines your level of seniority when you interview for a role.
The upshot is that whatever we do as designers have implications for the business and its customers. We need to meet or exceed customer needs by efficiently utilizing resources. Design questions are open ended, and they’re intentionally vague to start with. Learn about system design interviews (SDIs) and how to strategically approach them. You’ll still need to articulate a high-level design and defend your choices based on requirements and tradeoffs.
However, the RESHADED strategy is a general guideline that can be extremely helpful for effectively resolving just about any design problem. Let’s apply the above guidelines to design a few systems that are asked in SDIs. Such terminology also acts as a lingua franca between the interviewer and candidate. Another question in an SDI might be related to why we don’t design a system that’s already capable of handling more work than necessary or predicted. Designing and operating a bigger system requires careful thinking because designs often don’t linearly scale with increasing demands on the system.
Use diagrams, flowcharts, or any visual aids that can help you convey your ideas more effectively. This will make it easier for the interviewer to follow along and understand your thought process. When faced with a system design problem, it is important to approach it systematically. Take the time to clarify any ambiguities and ask questions to gain a deeper understanding of the problem domain. This will help you frame the problem in a way that allows you to design an effective solution. Remember, effective system design study requires a combination of theoretical knowledge and practical experience.
Understanding these components will help you make informed design decisions. Attending system design workshops, webinars, and conferences can also enhance your understanding and provide opportunities for networking with industry experts. These events often feature talks and discussions on the latest trends and best practices in system design. Microservices Architecture is a more recent methodology that builds on the principles of SOA but takes it a step further by breaking down the system into even smaller, independent services. Each microservice is responsible for a specific business capability and can be developed, deployed, and scaled independently. Microservices architecture enables agility, scalability, and fault isolation.
