Mastering Data Structures for Coding Interviews


Coding interviews don’t have to be nerve-wracking

So, you have an interview coming up. You decide it’s a good idea to refresh yourself on data structures. Sure, there are a lot of resources like blogs, videos, short tutorials, even practice questions on sites like LeetCode, but before you know it, you realize there’s way more that you need to cover than you initially thought and you spend more time searching for it than actually studying.

Just as an example, if you had an interview with Google coming up, they put right on their career page that interviewers should:

Study up on as many data structures as possible. Data structures most frequently used are arrays, linked lists, stacks, queues, hash-sets, hash-maps, hash-tables, dictionary, trees and binary trees, heaps and graphs. You should know the data structure inside out, and what algorithms tend to go along with each data structure.

The process of preparing for coding interviews is anxiety-inducing for many developers and it’s easy to see why. There’s so much material to cover, and we’re seeing developers spend their time combing through hundreds of interview questions and not really solidifying what they just learned.

One of the most common points of anxiety that developers face before an interview is: Have I solved enough practice questions? Could I have done more?

No need to ask yourself these questions anymore.

Don’t just memorize solutions, become a problem-solver

Interviewers have a keen eye for those who can memorize solutions and those who are true, gritty problem-solvers. Don’t be the former.

Rather than throwing a bunch of interview questions at you and expecting you to memorize them, these data structure courses focus on the process for solving these types of questions. Each problem is broken down and examined so that you can truly understand each and every step. Try a free preview of one of our data structure interview prep courses:

Created by the experts

Our data structure interview courses have been created and carefully vetted by former Senior Engineers and hiring managers from top tech companies in the tech industry, including Amazon, Microsoft, Google, and Facebook.

You’ll get the insider track on exactly what types of questions you can expect and how to implement the solution, giving you the confidence to handle a wide breadth of interview questions.


Learn at your own pace

Reading is faster than watching: the average video tutorial is spoken at 150 words per minute, while the average human reads at 250. That’s why our courses are laid out as rich text.

You’ll get all the benefits of reading from a book, such as the ability to skim over parts, double back easily where needed, and highlight passages you find particularly interesting.

We recognize learning visually is important. That’s why solutions are laced with detailed charts and visualizations. Try a free preview today:
