A review of LeetCode as a software engineer interview prep tool

Hi, I’m Brian, a former senior software engineer and now software engineering advisor at Pathrise. I work with hundreds of software engineers to help them land their dream job.

What does LeetCode do?

The mission of LeetCode is to help software engineers enhance their skills, expand their knowledge, and prepare for technical interviews. They have over 1050 questions, among their 3 skill levels – easy, medium, and hard and problem sets based on company questions (for Premium members). With hundreds of thousands of active users, including on their discussion board, they have one of the largest tech communities.

Users can participate in contests to challenge themselves and earn rewards. Some of these contests are sponsored by companies so that they can find top talent. They support 14 popular coding languages and give users access to powerful development tools, such as Playground, to help them test, debug, and write their own projects online.

Who is LeetCode for?

LeetCode is for software engineers who are looking to practice with technical questions and advance their skills. Mastering the questions in each level on LeetCode is a good way to prepare for technical interviews and keep your skills sharp. They also have a repository of articles, which are solutions to their questions with reasoning behind each step, so software engineers that are not as strong can also benefit from LeetCode.

What does LeetCode cost? How much work is involved?

There are some free questions and solutions on LeetCode, but for the most part, a subscription is necessary in order to fully make use of the service. Users can subscribe to a monthly package for $35 per month (down from $39) or a yearly package for $159 per month (down from $299). Premium users have access to more questions, solutions, more accurate company problem sets, and question sorting by prevalence. There is no application process.

Ratings and reviews

The reviews of LeetCode are all really positive. Most people find that similar online sources for software engineering questions are less organized, so they really appreciate the tagging and classification seen on LeetCode. Most users recommend doing easy & medium questions, as those are more likely to come up in some variance in interviews.

People are also complimentary of the solution articles, which they say are very helpful and should be looked at if you are stuck on a problem for more than an hour. Reviewing these solutions is helpful for candidates who see similar problems on their technical interviews as they will know the exact reasoning behind each step of the process.

Alternatives to LeetCode

There are other websites that compile software engineering questions, similar to LeetCode. A good option is AlgoExpert, which is a platform where software engineers can practice questions that cover a variety of interview topics. Get 15% off using the promo code: Pathrise.

HackerRank is another well known alternative. People say that the UI is nicer on HackerRank but the questions and content are sometimes less helpful. If you are looking for technical questions directly in your email, Daily Coding Problem is a newsletter that sends 1 problem a day and the solutions for those who subscribe. With exercises in Python and JavaScript for beginners and advanced engineers, CheckiO is a good free resource to check out.

Created by a former Google software engineer, Interview Cake is a study tool that teaches people the right way to think about technical questions so they do well in interviews.
