System design interview questions

Table of Contents • • • • • • • • • • • Introduction Coding and system design interviews are frequent—and pretty typical—in Big Tech and high-growth companies. The interviewer will expect you to provide a detailed description of how big-scale distributed systems (such as Twitter, Messenger, Netflix, Uber, and so on) were designed. This round may be complicated since you must cover all of the subjects and tradeoffs in the allotted period, which seems to be impossible. We don’t want the process to be as intimidating as it sounds for you, so let’s go through how to clear it step by step. Read through for some helpful suggestions for avoiding mistakes as well. What is System Design? The process of defining system aspects such as modules, architecture, components, and their interfaces, and data for a system based on the stated requirements is known as system design. It is the process of identifying, creating, and designing systems that meet a company’s or organization’s unique goals and expectations. Cracking System Design Interviews There are many approaches to • Demonstrates to the interviewer that you have the necessary knowledge. • Divides the problem into small stages. Let’s take a closer look. Ask clarifying questions To begin addressing a system design interview question, ask clarifying What is the system’s goal? If you’re requested to design an online bookstore, you should start by gathering more precise information about the bookstore’s objective: • What kind of shop i...

Written By Ryan Loftus | April 28, 2022 System design interviews have been a critical component of technical hiring for decades. If you’re a software engineer on the job market, the ability to demonstrate your skills in a design interview is critical to landing your next role. The key to succeeding in these interviews is preparing for the styles of problems you might encounter. In this post, we’ll break down seven different system design interview questions you need to know to land the next job of your dreams. What a System Design Interview Looks Like A system design interview is a type of interview that challenges candidates to design a back-end system, often on a physical or virtual whiteboard. Candidates are asked to verbally explain their solution and thought process as they develop their answer. System design questions grant candidates a look into an organization’s tech stack and operations and give hiring managers an understanding of the candidate’s approach to problem solving. These interviews should ideally proceed like discussions, with the candidate thinking aloud about scalability, storage, reliability, and other aspects of the system. System design interviews are more commonly found in hiring processes for senior-level roles, though developers of other experience levels may encounter this type of interview, as well. System design interviews are considered one of the more difficult types of interviews. They require a fundamental understanding of systems and adva...

You may have heard the terms "Architecture" or "System Design." These come up a lot during developer job interviews – especially at big tech companies. I wrote this in-depth guide when preparing for my FAANG software engineering interviews. It covers the essential software system design concepts you need to reason your way through distributed systems, and it helped me get into Google as an engineer, after more than 15 years of being a corporate lawyer. This is not an exhaustive treatment, since System Design is a vast topic. But if you're a junior or mid-level developer, this should give you a strong foundation. From there, you can dig deeper with other resources. I've listed some of my favourite resources at the very bottom of this article. I've broken this guide into bite-sized chunks by topic and so I recommend you bookmark it. I've found • • • • • • • • • • • • • Let's get started! Section 1: Networks and Protocols "Protocols" is a fancy word that has a meaning in English totally independent of computer science. It means a system of rules and regulations that govern something. A kind of "official procedure" or "official way something must be done". For people to connect to machines and code that communicate with each other, they need a network over which such communication can take place. But the communication also needs some rules, structure, and agreed-upon procedures. Thus, network protocols are protocols that govern how machines and software communicate over a give...
