Blind 75 vs NeetCode 150: Which List Should You Do?
The two most popular coding interview problem lists compared. Here is everything you need to decide which one to start with — or whether to do both.
TL;DR
Choose Blind 75 if...
- • You have 4-6 weeks to prepare
- • You want the highest-signal problems
- • You are short on time before an interview
- • You already know the basics well
Choose NeetCode 150 if...
- • You have 8-12 weeks to prepare
- • You want video explanations for every problem
- • You are targeting top-tier FAANG roles
- • You want broader pattern coverage

Our Recommendation
If you have less than 6 weeks: Start with Blind 75. Focus on the first 40 problems by pattern. You will cover the majority of interview scenarios.
If you have 6-12 weeks: Do NeetCode 150. The video explanations and broader coverage give you more confidence. The first 75 problems are exactly Blind 75.
If you already completed Blind 75: Do the 75 additional problems in NeetCode 150. Focus on the patterns Blind 75 missed: Tries, Union-Find, Monotonic Stack, Bit Manipulation, and 2D DP.
Either way: Use Coding Prep Guide to follow the pattern-based approach. Our roadmap orders patterns by importance and gives you curated problems at each stage.
