Who is LeetCode for?

LeetCode is for software engineers who are looking to practice 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 solutions with reasoning behind each step. Therefore, 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, and company problem sets, as well as better question sorting. 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.
