Job interviews can be very stressful. Sometimes, we struggle to articulate the concepts we work with on a daily basis. Even if we have sufficient knowledge in coding and design, we may not be as skilled in presenting this knowledge as we are in applying it in our projects. Preparation is the best thing we can do to succeed in an interview. In addition to coding skills, we need to be able to articulate the concepts we work with and clearly explain how they work and what problems they solve. This course is designed for that purpose. I have collected over 100 real Node.js interview questions that I or my colleagues have encountered. Although I answered these questions in interviews, I often left out important details. Especially when asked about in-depth knowledge of how Node.js works and why it is so good for the web, or questions about databases and proper practices for working with them. The goal of this course is to prepare you for such questions. We delve into the depth of each concept, understand the context of the questions, understand the underlying technologies used to solve the problem posed by the interviewer, and provide clear recommendations. Ultimately, there is no perfect solution, only compromises. To find the right solution, we need to understand these compromises.<\/span><\/p>\n<h3 dir=\"ltr\" style=\"text-align: left\" data-sourcepos=\"10:1-10:24\"><span style=\"vertical-align: inherit\">What you will learn<\/span><\/h3>\n<ul dir=\"ltr\" style=\"text-align: left\" data-sourcepos=\"11:1-18:0\">\n<li data-sourcepos=\"11:1-11:88\"><span style=\"vertical-align: inherit\">You will be able to describe the NodeJS architecture (event loop, event queue, Libuv workers).<\/span><\/li>\n<li data-sourcepos=\"12:1-12:139\"><span style=\"vertical-align: inherit\">You will be able to solve questions like \u201cin what order do these console outputs appear?\u201d based on a detailed knowledge of event loop phases and microqueues.<\/span><\/li>\n<li data-sourcepos=\"13:1-13:95\"><span style=\"vertical-align: inherit\">You will learn how to answer questions about how to build production applications.<\/span><\/li>\n<li data-sourcepos=\"14:1-14:175\"><span style=\"vertical-align: inherit\">You will learn how to answer questions about databases including database design, data normalization, server-side programming, and query optimization practices.<\/span><\/li>\n<li data-sourcepos=\"15:1-15:96\"><span style=\"vertical-align: inherit\">You will learn the fundamentals of system design \u2013 client-server model, caches, proxies, load balancing, etc.<\/span><\/li>\n<li data-sourcepos=\"16:1-16:94\"><span style=\"vertical-align: inherit\">You will learn how to work with data in NodeJS, including important errors in various APIs.<\/span><\/li>\n<li data-sourcepos=\"17:1-18:0\"><span style=\"vertical-align: inherit\">You will learn how to answer questions about practices such as examples of simulation, making fake objects, and espionage.<\/span><\/li>\n<\/ul>\n<h3 dir=\"ltr\" style=\"text-align: left\" data-sourcepos=\"19:1-19:30\"><span style=\"vertical-align: inherit\">This course is suitable for people who:<\/span><\/h3>\n<ul dir=\"ltr\" style=\"text-align: left\" data-sourcepos=\"20:1-24:0\">\n<li data-sourcepos=\"20:1-20:74\"><span style=\"vertical-align: inherit\">Beginner NodeJS developers preparing for NodeJS job interviews.<\/span><\/li>\n<li data-sourcepos=\"21:1-21:74\"><span style=\"vertical-align: inherit\">Intermediate NodeJS developers preparing for NodeJS job interviews.<\/span><\/li>\n<li data-sourcepos=\"22:1-22:78\"><span style=\"vertical-align: inherit\">Full-stack TypeScript developers looking to enhance their NodeJS knowledge.<\/span><\/li>\n<li data-sourcepos=\"23:1-24:0\"><span style=\"vertical-align: inherit\">Full-stack JavaScript developers looking to enhance their NodeJS knowledge.<\/span><\/li>\n<\/ul>\n<h3 dir=\"ltr\" style=\"text-align: left\"><span style=\"vertical-align: inherit\">Course Details NodeJS Interview Guide 100+ Questions &amp;
