What is LeetCode?

Question

I'm still in high school but keep seeing LeetCode in all of the interview question posts. What is it, actually? Do companies really use questions on there for their interviews?

It's like interview training, sort of. They host challenging problems and some companies will use those as the basis for their interview questions.

I remember having to do a leetcode type problem in my interview and it was the only time in my job I've run into anything like it lol, still not sure why they used it. Just wish I could remember what it was

They use them to evaluate your coding skills and understanding of data structures/types and algorithms. Definitely used in a lot of larger companies for SWE type positions, for better or worse.

You can Google the first part but for the second part, yes. I’ve had interviewers quite literally copy paste verbatim leetcode problems (valid palindrome, group anagrams, etc.) I’ve also had interviews with leetcode problems that were basically reskinned to look like an original problem (Top-K Words, max avg subarray) so yes it is possible for you to get an interview question straight from there

It is one of many coders’ puzzle platforms. Quite far from the software engineering and real tasks but yes, some companies still use it as a filter.
