AlgoExpert vs LeetCode

LeetCode and AlgoExpert are popular educational platforms that help you prepare for software engineering interviews.

The main difference between LeetCode and AlgoExpert is that LeetCode offers a wider range of questions to choose from while AlgoExpert focuses on providing in-depth explanations for each question. AlgoExpert is focused on helping people land jobs at FAANG companies while LeetCode is more popular among people who want to work in the tech industry in general.

In this article, we will compare and contrast AlgoExpert and Leetcode in content, features, and price.

You will learn about the pros and cons of each platform so that you can decide which one is right for you if you are preparing for a coding interview.

AlgoExpert is the ultimate Big Tech interview prep platform. AlgoExpert gives you all the resources you need to prepare for difficult software engineering questions. These include 160 hand-picked questions, over 100 hours of video explanations, data structure crash courses, solutions in 9 languages, space-time complexity analyses, and 4 curated assessments.

Clément Mihailescu, a former Facebook and Google software engineer, co-founded AlgoExpert. So, the platform’s content is created by experienced engineers who know what types of questions are asked in interviews. Clement and Tim Ruscica (a.k.a Tech with Tim) are the main instructors on AlgoExpert.

They also offer a feature-rich coding workspace, mock coding interviews, and a recruiting profile & certificate. These resources help you land the technical interview and ultimately the job you want.

AlgoExpert Programming Languages

AlgoExpert supports nine programming languages at the moment: JavaScript, TypeScript, Python, Swift, Kotlin, C++, Java, C#, and Go.

All video explanations are written in Python because it is the most popular language among interviewees.

AlgoExpert Features


AlgoExpert offers concise, step-by-step video explanations of how to solve coding interview questions. Each video is focused on a specific concept.

You start by understanding the high-level concept, then you walk through the initial implementation using Python. At the end, you work on optimizing and analyzing the algorithm.

If you are a visual learner, then AlgoExpert’s videos might be the best resource for you. The videos are well-produced and offer in-depth explanations of how to approach, optimize, and ultimately solve coding interview questions.

Programming Questions

AlgoExpert has 160 programming questions. They divided these problems into 15 categories, such as:

  • Arrays
  • Linked lists
  • Strings
  • Graphs
  • Binary trees

LeetCode contains over 1400 programming problems. They're classified from "easy" to "medium" to "hard."

Certificate of completion

You will get a Certificate of Completion for AlgoExpert when you finish.

It's a nice touch compared to LeetCode because there is currently no way to get a Certificate of Completion for LeetCode problems.

Data Structures Crash Course

AlgoExpert designed a Data Structures Crash Course to get you up to speed with important data structures.

The course covers topics such as memory, complexity analysis, and big O notation. You will also learn about logarithms, linked lists and binary trees.

The Data Structures Crash Course serves as a fundamental basis for your interview prep. There are 13 video sections with around 5 hours of content in total.

Mock Coding Interviews

Mocking a coding interview is a powerful feature because nothing prepares you better than talking to another person.

AlgoExpert has two options for mocking coding interviews:

  • With a random AlgoExpert user
  • With a friend

AlgoExpert lets you schedule a meeting with another user using a "Scheduler" feature on the website. Interviews are usually an hour long, so you get 2 hours total to alternate between being an interviewer and interviewee.

The interview is conducted in a shared coding workspace that looks the same as the workspace you use for practicing except you can't see the solution.

If you are looking for a practice partner for interview prep, then AlgoExpert is worth it. LeetCode doesn't have a live interview mocking feature.

AlgoExpert Pricing

AlgoExpert costs $119 for 1-year access.

Programming Questions

LeetCode is a site where students and professionals can come to learn how to code. They have different sections, like Featured - Coding Challenges, where you can find coding challenges and questions for interviews. There's also a section called Interview, which has tasks for people who are interviewing for jobs.

LeetCode challenges are available for free every day. This includes the 30-Day LeetCode Challenge, the May LeetCode Challenge, and the June LeetCode Challenge. Some challenges may be out of date.

If you don't need the guidance that AlgoExpert offers, then LeetCode may be a better option for you.

Community Discussions

The LeetCode community is a great place to find help with coding problems.

In addition to being helpful, the community is also a valuable resource for salary negotiation, interview preparation, and career development.

LeetCode has a lot more users than AlgoExpert, so the community aspect of LeetCode is much stronger.

LeetCode Data Structures and Algorithms Crash Course

LeetCode also has a Data Structures and Algorithms Crash Course that competes with AlgoExpert's Data Structures Crash Course. However, LeetCode's Crash Course is not included in the yearly premium membership. It'll cost you an additional $34.99 to take it.

Quality-wise, LeetCode covers more topics. LeetCode uses a combination of text and video content to help you learn, while AlgoExpert mainly focuses on video content.

AlgoExpert vs LeetCode: Conclusion

If you want to focus on algorithm development and learn from focused explanation videos, AlgoExpert is better than LeetCode. If you're looking for a large selection of programming challenges to practice with, LeetCode is the way to go.

AlgoExpert and LeetCode are both useful tools for acing interview questions. AlgoExpert has smaller problem sets with focused explanation videos, while LeetCode is famous for its large programming assignments. Both platforms offer a complete coding environment built-in. Additionally, LeetCode offers premium challenges that can help you prepare for interviews with specific Big Tech companies.


AlgoExpert is tailored for Big Tech interviews. Compared to LeetCode, AlgoExpert gives you more guidance, which is great if this is your first time dealing with algorithms.

I like how it provides a clear path to success: You'll probably want to start with the Data Structure Crash Course, which consists of thirteen videos. Then, you'll move to AlgoExpert's bank of 160 hand-picked questions. When ready, AlgoExpert lets you schedule a mock interview with a random AlgoExpert user or one of your friends.

Keep in mind that all video explanations use Python.


LeetCode is famous for its large programming assignments, whereas AlgoExpert is known for its smaller problem sets with focused explanation videos. Both platforms offer a complete coding environment built-in. LeetCode is a code school where you can learn about data structures and algorithms. They also have great practice problems for interviews.

Unlike LeetCode, AlgoExpert doesn't have a community section on the site.
