Course Overview

Coding interviews are becoming increasingly challenging. A few years back, brushing up on key data structures and going through 50 to 75 coding interview questions was more than enough prep for an interview. Today, everyone has access to massive sets of coding problems, and they have become more difficult to account for. The process has gotten more competitive. When our team sat together to brainstorm on ideas to make the interview process easier for candidates, we realized quickly that one skill helped us the most when we were preparing for coding interviews: "the ability to map a new problem to an already known problem." To help candidates with this, we have compiled a list of 33 common coding patterns to help solve coding questions. The idea is that once you are familiar with a pattern, you'll be able to solve dozens of problems with it. The techniques taught in this course have helped developers land jobs at top companies like Google, Meta, Amazon, Oracle, OpenAI, and Microsoft.

What people say about our courses

Ashley Pean

Software Engineer

Check out Grokking the Coding Interview. Instead of trying out random Algos, they break down the patterns you need to solve them. Helps immensely with retention!

Simon Barker

Software Engineer

This is what I love about http://designgurus.io’s Grokking the coding interview course. They teach patterns rather than solutions.

Roger Cruz

Software Engineer

The world gets better inch by inch when you help someone else. If you haven't tried Grokking The Coding Interview, check it out, it's a great resource!

pikacodes

Software Engineer

I've tried every possible resource (Blind 75, Neetcode, YouTube, Cracking the Coding Interview, Udemy) and idk if it was just the right time or everything finally clicked but everything's been so easy to grasp recently with Grokking the Coding Interview!

Matzuk

Software Engineer

Algorithms can be daunting, but they're less so with the right guide. This course - http://www.designgurus.io/course/grokking-the-coding-interview, is a great starting point. It covers typical problems you might encounter in interviews.

Tonya Sims

Software Engineer

DesignGurus.io "Grokking the Coding Interview". One of the best resources I’ve found for learning the major patterns behind solving coding problems.
