Our coding interview prep isn't based on arbitrary brainteasers. Whether you're paginating attendees in a Zoom call or working on Netflix's recommendation system, everything you learn will be practical, relevant, and memorable.

Get your hands dirty

Watching videos doesn't improve your coding. You need hands-on, interactive experience to practice before you get into an interview. No need to switch to your IDE, download an SDK. You can learn right inside your browser.

Break down 100+ problems

Our team of experts has combed through the most commonly asked interview questions at top tech companies and incorporated them into a carefully crafted set of scenarios for you to learn from.

Interview with confidence. Accelerate your career.

What you'll learn

The most commonly asked questions

In each section, you'll learn the most frequently asked questions that are posed in an interview. These questions have been carefully selected to give you the best experience.

How to solve a problem in the context of building features

This course takes ordinary interview questions and frames them in the light of what software engineers do everyday - build features and products. Instead of just mindlessly going through interview questions, it gives you a chance to understand how these questions relate to the real-world.

How to think like a problem-solver

This is probably the most important. Through this course, you won't be memorizing solutions, instead you will learn how to think like a problem-solver.

Educative was very useful to prepare for interview at Google. I always recommend it to my friends.

Mikhail Olkhovskiy - Senior Software Engineer at Google

Your courses are simply awesome, the depth they go into and the breadth of coverage is so good that I don't have to refer to 10 different websites looking for interview topics and content. The collection of questions / problems / exercises you have is excellent.

Vinay Krishnaiah - Chief Architect

Today I accepted my offer letter at Google and I would like to thank you personally for helping me achieve it. Without your resources, this would not have been possible and for that I am truly grateful.
