Coding is undoubtedly the career of the future. In 2018, 71% of STEAM jobs were in computing and programming. At Insiderbits, we urge you to take advantage of every detail of this post to learn more about LeetCode.

What is LeetCode about?


Initiated in August 2015, LeetCode is an Internet platform dedicated to coding interview preparation. Besides, it allows its users to learn coding by challenging them to solve algorithmic and programming complications.

LeetCode has gained significant popularity among coding fans and job seekers. It offers both technical interviews and coding contests, explaining the above.

This tool has a free option and a paid alternative. The first only allows access to a restricted number of requests. The second offers access to additional requests previously asked in interviews in large technology companies.

LeetCode features

The creators of LeetCode describe it as a new method of learning. Moreover, they consider it an ideal platform to help users strengthen their coding skills. In addition, it allows them to expand their knowledge and train for technical interviews.

When you visit this tool’s website, you will find several categories: Start Exploring, Questions, Community & Answers, Companies & Candidates, and Developers. Next, we will delve into each of them.

Questions, Community & Contest

You have access to more than 3350 questions in 3 difficulty levels to train yourself. Of them, 771 are classified as easy, 1,599 as medium difficulty, and 675 as complex. A characteristic category or tag distinguishes each question posed by LeetCode. Among the most common, we can mention the following:

  • Arrays.
  • Chains.
  • Two pointers.
  • Batteries.
  • Binary search.
  • Sliding windows.
  • Linked lists.
  • Trees.
  • Attempts.
  • Backtracking.
  • Lots.
  • Priority queues.
  • Graphics.
  • Breadth search and depth search.

Other labels, such as dynamic programming, greedy algorithms, bit manipulation, database problems, and mathematics, also stand out.

To all this, it must be added that its creators qualify LeetCode as one of the technological communities with the most active users. The same platform is in charge of continually challenging them with contests that allow them to obtain rewards. We will delve into this point later.

Companies & Candidates

In addition to preparing applicants for technical interviews, LeetCode assists companies in finding top technical talent. In addition to the above, LeetCode also delivers organization evaluations, online training, and contest sponsorship.


The main basis of LeetCode is coding and programming. For this, it has development tools such as Playground. All these aids serve to support the user in the process of testing, debugging, and writing their projects.

How does LeetCode work?

The platform’s operation is simple. Each user must answer the interrogations asked by LeetCode. It then evaluates the solution’s performance based on its efficiency and how quickly it was carried out. Once this is done, LeetCode compares that solution with others in its database and categorizes it.

Another characteristic of LeetCode is that it gives access to mock interviews and online assessments. Likewise, it organizes weekly and biweekly contests with four problems each. The platform also provides users with daily challenges and the possibility of participating in raffles.

It supports JavaScript, C, Python, and Java, which stand out. In contrast, customers can participate in their forums. They are discussion spaces that inspire debates related to the problems and the interview process. Besides, they allow each person to share their experience during the interview.

LeetCode: an excellent method to learn coding

Along these lines, we have explained the general terms of the LeetCode platform and how to use it. Considering the relevance of programming today, it is an option worth trying at Insiderbits.
