A direct comparison for candidates preparing for tech interviews in 2026
Most people preparing for coding interviews start with LeetCode. It has a huge library of algorithm problems and an active community. PracHub does something different: it collects the actual questions candidates report being asked at specific companies, and it covers interview types that LeetCode does not touch — SQL, system design, machine learning, behavioral, and product sense. The table below breaks down where each platform is stronger.
| Feature | PracHub | LeetCode |
|---|---|---|
| Question Source | Real questions from verified candidate interviews | Community-submitted and curated algorithm problems |
| Question Types | Coding, SQL, System Design, ML, Behavioral, Product Sense, Statistics | Primarily coding and algorithms, some SQL and system design |
| Total Questions | 7,500+ across all categories | 3,000+ coding problems |
| Company Tags | 50+ companies with verified interview data | Company tags available (premium) |
| SQL Practice | In-browser SQL editor with real interview queries | SQL problems available, limited editor |
| System Design | 850+ system design questions with solutions | Limited system design content |
| Behavioral Questions | 1,000+ behavioral questions by company | Not covered |
| Machine Learning | 580+ ML interview questions | Not covered |
| Free Tier | Browse all questions, select solutions free | Limited free problems, most behind paywall |
| Interview Context | Company, role, round, difficulty per question | Difficulty level and topic tags |
Candidates interviewing for data science, data engineering, ML, or product roles where interviews go beyond coding. Also candidates who want to know exactly which questions specific companies ask.
Candidates focused purely on algorithm-heavy interviews at companies that test primarily on LeetCode-style problems. Competitive programmers who value the contest system.
PracHub covers a wider range of interview types than LeetCode, including SQL, system design, machine learning, behavioral, and product sense questions. If your interviews include non-coding rounds, PracHub fills the gaps that LeetCode does not cover.
Yes. PracHub has 2,400+ coding and algorithm questions with an interactive coding environment. The difference is that these are sourced from real interviews rather than generated as abstract problems.
Yes, and many people do. A common setup is LeetCode for algorithm drilling and PracHub for company-specific prep, SQL practice, system design, and behavioral rounds.
FAANG interviews test coding, system design, and behavioral skills. LeetCode covers coding well. PracHub covers all three, with verified questions tagged by company and round, so you know what to expect in each stage.
PracHub offers a free tier that lets you browse all 7,500+ questions. Premium access unlocks all solutions, the coding environment, SQL editor, and learning courses.
