AlgoExpert
AlgoExpert
Curated 160-problem DSA set with high-quality video explanations. Strong production value but limited problem coverage at premium pricing.
Pros
- + High production quality. Video explanations are among the best in the category.
- + Curated 160-problem set avoids the noise of LeetCode
- + Space and time complexity analysis included for every solution
- + Systems design module covers 15 problems
- + Clean, fast interface
Cons
- – Expensive relative to alternatives ($99+/year)
- – 160 problems is limiting. Insufficient for companies with large question pools.
- – Systems design module is shallow compared to dedicated courses
- – No pattern-based framing. Problems are categorized but not taught as patterns.
Verdict
A polished secondary resource, not a primary one. The video explanations are genuinely excellent and worth watching for problems where you are stuck. But at this price point, Grokking's coding course delivers more value. Use AlgoExpert to supplement, not replace, a pattern-based DSA course.
Overview
AlgoExpert is a curated DSA platform featuring 160 hand-picked problems with video explanations by Clement Mihailescu. It positions itself as a quality-over-quantity alternative to LeetCode's thousands of problems.
What You Get
- 160 curated coding problems (Easy/Medium/Hard/Very Hard)
- Video solutions with time/space complexity walkthrough
- Written solutions in 9 languages
- Systems Expert: 15 system design problems with video (separate subscription)
- Behavioral interview prep module
Who It's Best For
Engineers who learn better from video explanations than written solutions, and who want a smaller, curated problem set rather than an overwhelming bank.
The Production Quality Argument
AlgoExpert's video explanations are genuinely excellent. Clement is a clear, methodical explainer. For problems where you read a solution but can't internalize why it works, watching the video walkthrough often unlocks understanding.
The Value Problem
At $99+/year for the coding module (and additional cost for Systems Expert), the pricing is hard to justify as a primary resource when pattern-based alternatives cost similar amounts and cover more ground with a superior pedagogical approach.
The 160-problem cap also matters for company-specific prep. Companies like Amazon and Google have large question pools. A curated 160-problem set gives you strong foundational coverage but may miss company-specific questions.
Recommendation
If budget permits, use AlgoExpert as a supplement to Grokking the Coding Interview, specifically for problems where you want a video walkthrough. Do not use it as your only coding prep resource.
