Frequently Asked Questions
What is Grokking the Coding Interview?
Grokking the Coding Interview is an educational resource specifically designed to help users prepare for software engineering interviews. It is structured as a course that breaks down typical coding interview problems into recognizable patterns, teaching the strategies, and problem-solving techniques necessary to tackle these effectively. It further helps learners deeply understand these patterns so they can efficiently solve a wide range of problems without having to memorize extensive problem sets. This focus on pattern recognition over rote memorization helps candidates approach interviews with a stronger, more strategic foundation. The course explains a series of common problem-solving patterns that are frequently asked in coding interviews. These patterns include, but are not limited to:
In addition, Educative offers Grokking the Coding Interview in 5 languages: Java, Python, C++, Go, and JavaScript.
