Both lists dominate interview prep. The honest comparison: what each covers, what each misses, and which to do based on your timeline.
What is the Blind 75?
The Blind 75 was created by an anonymous engineer posting on Blind (the professional network) in 2018. It is 75 curated LeetCode problems across 9 topics chosen to maximize coverage of interview patterns at top tech companies. Still the most referenced list for FAANG/MAANG prep. Organized by: Arrays, Binary, Dynamic Programming, Graph, Interval, Linked List, Matrix, String, and Tree/Heap.
What is NeetCode 150?
NeetCode 150 is an extension created by YouTuber NeetCode (Navdeep Singh) that expands the Blind 75 to 150 problems, adding coverage of important patterns that Blind 75 skips: Bit Manipulation, Math & Geometry, Stack, Tries, and Backtracking. It also reorganizes the categories for better learning progression. If you have already done Blind 75, NeetCode 150 fills the gaps.
Head-to-head comparison
Timeline — Blind 75 takes 4–6 weeks, NeetCode 150 takes 8–12 weeks. Coverage — Blind 75 covers 9 topics, NeetCode 150 covers 16 topics. Difficulty distribution — Blind 75 is roughly 40% Medium/Hard, NeetCode 150 is more balanced. Video solutions — NeetCode 150 has video explanations for every problem; Blind 75 does not. For FAANG breadth — NeetCode 150 wins. For short timelines — Blind 75 wins.
Which one should you do?
Under 4 weeks → Blind 75, prioritize the top 40 by pattern. 4–8 weeks → Blind 75 first, then add NeetCode extras. 8+ weeks → NeetCode 150. Already did Blind 75 → Do the 75 problems NeetCode 150 adds. FAANG/MAANG targeting in the US → NeetCode 150 gives more breadth and confidence, while Blind 75 covers most non-FAANG companies. In India → Blind 75 is sufficient for most non-FAANG companies.
The verdict
Don't obsess over the list — obsess over the pattern. Both lists are vehicles for pattern recognition. If you truly understand Two Pointers, Sliding Window, BFS/DFS, DP, and Binary Search you can solve problems that appear on neither list. The list is a curriculum, not the destination.
Frequently Asked Questions
Should I do Blind 75 or NeetCode 150? +
If you have 4-6 weeks, do Blind 75 — it is the highest-signal list for the time investment. If you have 8-12 weeks and are targeting top-tier FAANG companies, do NeetCode 150 — it adds 75 problems covering Tries, Advanced Graphs, 2D DP, and Bit Manipulation that Blind 75 skips. If you have already completed Blind 75, do the 75 additional problems NeetCode 150 adds.
Is the Blind 75 list still relevant in 2026? +
Yes. The Blind 75 was created in 2018 but the problems remain highly relevant because they test fundamental algorithmic patterns that have not changed. Companies like Google, Meta, and Amazon still ask variants of these exact problems. The patterns (Two Pointers, BFS/DFS, DP, Binary Search) are timeless — only the problem framing changes.
How long does it take to complete NeetCode 150? +
Most engineers take 8-12 weeks at 2-3 problems per day with proper understanding. Rushing through in 4 weeks by memorizing solutions defeats the purpose. The goal is pattern recognition — being able to identify the right algorithm within 60 seconds of reading a new problem. That takes time and repetition, not just completion.
What is the difference between Grind 75 and Blind 75? +
Blind 75 is organized by data structure category (Array, Graph, DP). Grind 75 is curated by Tech Interview Handbook and organized by pattern (Stack, Two Pointers, BFS). Both have 75 problems and significant overlap. Grind 75 tends to be slightly more recent and includes some problems Blind 75 misses (like Implement Queue using Stacks). Either list works — the pattern matters more than the specific list.
