Data Structures? They're here. Algorithms? Covered. Lots of questions with well-explained solutions? Indeed! If you're nervous about your first coding interview or anxious about applying for your next job, this is the course for you. I got tired of interviewers asking tricky questions that can only be answered if you've seen the problem before, so I made this course! This video course will equip you with the most common interview questions you'll encounter in a coding interview, providing you the tools to ace your next whiteboard interview.

Course Highlights

Coding interviews are notoriously intimidating, but there is one method to become a better interviewer - and that is practice! Practicing dozens of interview questions can make the difference between receiving a job offer for a $120k USD and receiving another rejection email. This course is designed to not only give you dozens of questions to practice but also ensure you understand the tricks behind solving each question, empowering you to perform confidently in a real interview.

Why Enroll in This Course?

I have dedicated countless hours reviewing interview questions from top companies like Google, Facebook, and Amazon to ensure you are prepared for questions asked by some of the highest-paying tech giants. No stone is left unturned as we cover everything from the simplest to the most complex algorithm questions.

What You'll Gain:

  • Clear, well-diagrammed explanations for every problem to ensure you understand the solution.
  • An overview of the most important data structures to know, tailored for those without a CS degree.
  • A comprehensive collection of common algorithm questions, from 'reversing a string' to 'determining the width of a BST'.
  • Effective strategies for tackling systems design problems.
  • Insider tips on what interviewers are truly seeking in responses.
  • Ongoing support on the Udemy Q&A forums from me!

My aim with this course is to help you vanquish those interviewers who pose challenging algorithm questions. Sign up today to become a leading-edge engineer ready for a high-paying job.

About the Authors

Stephen Grider

Stephen Grider thumbnail

Stephen Grider is one of the longest-running and most prolific instructors on Udemy, with a catalog covering essentially every major JavaScript framework, plus Docker, Kubernetes, AWS, and the broader full-stack development landscape. His teaching style is patient and project-oriented — most of his courses are structured around building a substantial application from scratch rather than working through disconnected tutorial examples.

The catalog covers React, Redux, Next.js, Vue, Angular, GraphQL, Node.js, Docker / Kubernetes, AWS infrastructure, React Native and Flutter for mobile, the algorithm / data-structure interview prep track, and the modern TypeScript / Bun / Rust adjacent material that working JavaScript developers increasingly encounter. Few independent instructors have maintained Stephen's breadth this consistently for this long.

The CourseFlix listing under this source carries over 25 Stephen Grider courses spanning that range. Material is paid; Stephen Grider courses are typically sold individually on Udemy. Courses are aimed primarily at developers picking up a specific technology through working through a complete project.

Udemy

Udemy thumbnail

Udemy is the largest open marketplace for online courses on the internet. Founded in 2010 by Eren Bali, Oktay Caglar, and Gagan Biyani and headquartered in San Francisco, the company went public on the Nasdaq in 2021 under the ticker UDMY. The platform hosts well over two hundred thousand courses across software development, IT and cloud, data science, design, business, marketing, and creative skills, taught by tens of thousands of independent instructors. Roughly seventy million learners use it worldwide, and the corporate arm — Udemy Business — supplies a curated subset of that catalog to enterprise customers.

Because Udemy is a marketplace rather than a single editorial publisher, the catalog is uneven by design. The strongest material lives in the long-form, project-based courses authored by working engineers — full-stack JavaScript, React, Node.js, Python data science, AWS, Docker and Kubernetes, mobile development with Flutter and React Native, and cloud certification preparation. The CourseFlix listing under this source is the slice of that catalog that has been mirrored here for offline-friendly viewing, organized by topic and updated as new releases land. Pricing on Udemy itself swings dramatically with the site's near-permanent sales, which is why the platform is best treated as a deep reference catalog: pick instructors with strong reviews and a track record of updating their material rather than buying on the headline price alone.
