LeetCode

The most recommended of 8 coding practice platforms

People recommend it for practicing the algorithm problems used in technical interviews, and say the free version is enough for standard interviews. The most common caveat is that critics say it rewards interview tricks more than real engineering.

  • Practice for technical interviews

    “Practice leetcode + hello interview, as almost every place will have some sort of leetcode round and system design round.”

    “I still do it to brush up my problem-solving skills and fundamental understanding of systems and data structures”

    Comment from 14 Apr 2026 in “Ask HN: LeetCode, anyone still doing it?”

    “Doing leetcode absolutely makes your system design better and you don't deploy algorithms you don't know.”

What people warn about

Each mark is one comment

  • Tests interview tricks, not engineering

    “Grinding leetcode was never optimizing for solving problems algorithmically but for performing well in live coding interviews.”

    Comment from 15 Apr 2026 in “Ask HN: LeetCode, anyone still doing it?”

    “Leetcode does not test your ability to code in the sense of anything related to real world engineering applications.”

    Comment from 19 Sep 2026 in “Jobs Without LeetCode”

    “LeetCode can impossibly teach you how to create useful programs, it only teaches you syntax and specific problems.”

    Comment from 9 Dec 2025 in “Show HN: AlgoDrill – Interactive drills to stop forgetting LeetCode patterns”
  • Takes time away from other work

    “I became a worse developer because I spent time on Leetcode instead of my open source projects, but it taught me marathon long grind.”

    Comment from 12 Oct 2026 in “Sorry we made you grind LeetCode”

    “leetcode grinding makes me feel like all my 10+ years of commitment to my previous employer”

    Comment from 12 Nov 2025 in “Ask HN: How does one stay motivated to grind through LeetCode?”
  • Interviewers often poorly prepared

    “Any company still using LeetCode at all during interviews is signaling that either they are run like a frat house”

    Comment from 9 Dec 2025 in “Show HN: AlgoDrill – Interactive drills to stop forgetting LeetCode patterns”

    “I've almost always seen the LeetCode grilling be administered by someone who doesn't know what they're doing”

    Comment from 2 Nov 2025 in “AI Broke Interviews”

    “It is a waste of everyone's time because they will either do it and think 'ok, that was weird'”

    Comment from 5 Mar 2026 in “Stop the Interviews”
  • Favors younger, recent graduates

    “I think Leetcode does weed out older folks, not necessarily because of skill, but because of the time needed for practice.”

    Comment from 5 Feb 2026 in “Why More Companies Are Recognizing the Benefits of Keeping Older Employees”

    “this type of interview is biased toward younger out of college hires and codecamp hires”

    Comment from 30 May 2026 in “The Last Technical Interview”
