If you’ve ever driven in a new city, Google Maps, Waze, or Apple Maps was probably your best friend and crutch — for good reason! Navigating new paths and roads can be stressful, and without maps or guidance, you’re prone to making mistakes.

With the simple idea of helping developers prepare for interviews, CodingInterview.com provides the roadmap for landing your next job at a top tech company. You’ll find that the more you know about the interview process, the easier it is to navigate.

Similar to the differences between cities, each company has its process and style of interviewing candidates. That’s where CodingInterview.com comes into the picture. Free interview guides are sourced from hiring managers and developers who have gone through the interview process at their respective companies.

Let’s take a look at how CodingInterview.com breaks your next interview into proven-to-work and straightforward steps.

Interview Roadmap and Coding Interview Prep

The Definitive Interview Prep Roadmap was written by Fahim Ul Haq, Ex-Facebook, Ex-Microsoft, and Co-founder of Educative. Having interviewed hundreds of candidates for software engineering jobs and even failing at several coding interviews himself, Fahim pulls from his personal experience to provide a 3-month Self-Study Roadmap.

12 Week Breakdown

For 12 weeks, you’ll dive into five main sections that all “Big Tech” companies hold in common. Think of this section as a generalized roadmap of topics and subjects that all companies overlap on. Like multiple Venn diagrams falling in place, the Definitive Interview Prep Roadmap falls at the center. Those five main sections include:

  • Coding Interviews (focusing on problem-solving, data structures, and algorithms)
  • OS and Concurrency Concepts
  • System Design Interviews
  • Object-Oriented Design Interviews
  • Behavioural Interviews

Each section further breaks down each topic into specific concepts or problems. As a preview, here’s what you should expect:

Coding Interview Prep

Developers learn by doing. So instead of passively watching videos, Coding Interview Prep provides some guidance to courses that involve interactive challenges and playing with real code right from your browser. In this section, you’ll find links to detailed learning paths for the following coding languages:

In addition to choosing a language to practice, you’ll find links to data structures and system design courses. Each course focuses on vital concepts you need to know for an interview while testing your knowledge through interactive challenges. Even after landing a job, you’ll find that the material covered in these courses will be helpful at any stage in your career.


Interview Guides by Company

With 20 different interview guides by company, each guide provides an insider’s look at how companies interview, what they test on, and how each process is different. By taking a couple of minutes to read through your respective guide, you’ll leave with a better understanding of how to prepare and practice the right material.

As of today, CodingInterview.com provides interview guides for the following companies (with more on their way!):

The Coding Interview

With simplicity and predictability, every company’s interview guide has a consistent format. Let’s dive into what you should expect:

1. Reading about the process

In this section, you’ll find a comprehensive explanation of every step between prescreens to receiving an offer letter. Whether you have prior experience with interviews or not, you might be surprised to find information unique to each company’s interview process. Take, for example, the Apple interview. You’ll most likely find yourself on FaceTime or Skype for a phone screen or ordering a light dish at a team lunch to maintain more extended conversations.

Along the way, you’ll find links to courses that may help your preparation for each step. Courses like Grokking the Behavioral Interview provide essential lessons to navigate behavioral and cultural questions asked by every company.

2. Exploring Common Questions

Time to get technical. Every interview guide supplements your preparation with answers to questions commonly asked by a specific company. The best part? Each question uses Educative’s built-in coding environment to provide hands-on practice without the hassle of installation or switching windows.

3. Considering Pros and Cons

This section scopes out the lay of the land at companies by providing testimonials from people who’ve worked there. As you’re contemplating which company to apply for, it’s helpful to consider whether you fit the work culture. You’ll find it easier to interview when you see yourself working in a specific company’s environment.

4. Personal Experiences and Additional Information

A video and testimonial supplements every guide with a transparent picture of interviewing and working at a company. With additional links and resources, you’ll spend less time surfing the web and more time preparing for interviews. You’ll find it more efficient to start at this page to expedite your interview prep journey.
