  • …and a few more.

Every interview question has several solutions, video explanations, output, and test cases.

LeetCode

interview questions LeetCode

LeetCode offers 2500+ interview questions spanning up to 70 programming categories.

The most popular category is Array, with over 1400 questions. Next is String with 624, and then Hash Table with 487. LeetCode updates the questions frequently, where new ones are added and others removed. This means the count is not static.

Other excellent categories include **database, sorting, dynamic programming, **and JavaScript. (ideal for frontend developers)

What makes LeetCode shine over AlgoExpert is that you can sort questions by company. They feature tons of questions from top tech companies like Apple, Uber, Microsoft, and Adobe.

Winner

Again, LeetCode wins in this category — with over 2500 interview questions against AlgoExpert, which has 195.

Video Explanations

AlgoExpert

Vide explanation AlgoExpert

AlgoExpert provides 100+ hours of video content. The videos include explanations of each interview question on the platform.

With AlgoExpert, you get two types of video explanations:

  • Conceptual overview: The instructor explains the programming concept, including how to approach, analyze, and optimize the solution.
  • Code walkthrough: The second part covers the code implementation from start to end.

Note: While AlgoExperts’ videos provide a step-by-step process, they are only available in Python.

Nonetheless, the videos are of excellent quality, and the audio is generally great.

LeetCode

Video explanation LeetCode

The LeetCode explore section offers users access to video explanations under two categories:

  • Learn - features videos of 22 programming concepts.
  • Interview - features videos of 18 interview concepts, including interviews from companies like Microsoft, Facebook, and Uber, among others.

In the Learn Section, each concept gives you 20 hours of video — meaning you get at least 440 hours of video.

However, some videos in the learn section include parts of LeetCode courses. Some of them have independent and relatively higher costs. Other video materials also require you to pay for LeetCodes’ premium subscription.

Winner

Once again, LeetCode wins in this category. However, AlgoExpert’s video structure is also ideal for beginners as it offers a more structured approach to tackling questions.

Pricing

AlgoExpert

Pricing AlgoExpert

AlgoExpert premium subscription starts at $99 per year. Nevertheless, this is merely one of the numerous pricing plans available should you decide to upgrade to a premium account.

LeetCode

Pricing LeetCode

LeetCode has a more straightforward pricing tier with two pricing plans. These include:

  • Monthly Plan: $39/month
  • Yearly Plan: $159/year

Winner

Concerning affordability, AlgoExpert wins — it’s the cheaper alternative. However, it is important to note that subscriptions for both websites come with additional features of their own, making the choice of one over another ultimately subjective.

LeetCode vs AlgoExpert: Pros And Cons

LeetCode Cons

  • Some video explanation materials are independent and more expensive
  • Quality–wise, video explanations aren’t in-depth

LeetCode vs AlgoExpert: Which is Ideal for a Frontend Developer?

As a frontend developer, you may wonder which platform is ideal for your interview questions. We assessed a few factors and determined that AlgoExpert is a better platform for frontend development than LeetCode for the following reasons:

  • AlgoExpert has a larger focus on frontend development, with over 50 frontend-specific problems. They have an entire package dedicated to frontend development spanning four categories. These include HTML, CSS, JavaScript, and DOM Manipulation. LeetCode has a slightly higher number (57) of frontend problems. However, these problems are only limited to JavaScript rather than any other areas of frontend development.
  • AlgoExpert's problems are more realistic and representative of the problems that frontend developers face in the real world. LeetCode's problems are often more theoretical and abstract, which can be less helpful for frontend developers.

Conclusion

Throughout this analysis of AlgoExpert and LeetCode, we delved into two remarkable platforms for coding interview preparation.

AlgoExpert caters to learners with its curated set of 190+ hand-picked questions and expert video explanations. In contrast, LeetCode offers a more extensive library of 2500+ coding problems and supports a wide range of programming languages.

That said, due to its cheap pricing, AlgoExpert stands out as an ideal platform for frontend developers looking to practice interview questions or users looking for a cheaper alternative. However, if you want to prepare for general software development, we recommend choosing LeetCode as it has a large pool of resources and materials.

As you embark on your coding journey, consider your preferences, learning style, and goals to select the platform that aligns best with your needs.
