Udemy – NodeJS Interview Guide 100+ Questions & Answers 2024-12

NodeJS Interview Guide 100+ Questions & Answers Course. 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.
