Grokking the Coding Interview COURSE REVIEW

Grokking the Coding Interview: Patterns for Coding Questions is an interactive interview prep course for aspiring FAANG engineers. The secret sauce of the course is 16 patterns that help you map a new problem to an already known problem.

It’s been said before, but interviewing for FAANG companies is its own skill set.

I’m an enthusiastic affiliate of Educative.io and may get compensated if you buy something. Read my disclosure for more details.

While there’s debate surrounding their effectiveness, the reality is that these interviews are part of FAANG (Facebook, Amazon, Apple, Netflix) workplace culture.

As a result? FAANG engineer interview prep courses are their own cottage industry now. From Leetcode to Codewars to hackerrank to AlgoExpert, more seem to pop up weekly.

And although Grokking the Coding Interview: Patterns for Coding Questions does cost money, the price is modest compared to your earnings once you pass your interview and receive an offer from a FAANG.

While this course is relatively new, it may be easy to pass over when so many free resources are available. But checking out Grokking the Coding Interview further, there are a lot of added features the free stuff just doesn’t offer.

For example, the robust coding playgrounds feature environments available for Java, Python3, JavaScript and C++ right in the browser:

This feature alone not only saves you the step of setting up a coding environment, but if you’re only using one screen, you eliminate the need to click from app to app. It’s kind of a boss move.

The Secret Sauce: 16 Patterns

One of the advantages Grokking the Coding Interview has over other platforms is that it features a clear, succinct strategy that emphasizes 16 patterns. In other words, it doesn’t just dive right into random coding problems and expect you to solve them.

Then, once you understand the pattern, you’ll be able to solve multiple problems using it.

You also get plenty of visual aids and interactive bits to help you. Including:

• 1000 code playgrounds (there’s an IDE right in the browser)
• 220 illustrations
• 125 challenges
• 184 lessons

…this course comes equipped with all the extras. Plus there’s a help section in each chapter for your questions.

Some of the 16 patterns you’ll learn include:

• Merge Intervals
• Two Pointers
• Sliding Window
• Tree Breadth First Search
• Two Heaps
• Subsets
• Top ‘K’ elements
• Topological Sort (Graph)

And many more.
