Blind 75 vs NeetCode 150 vs LeetCode 75: Which List Should You Follow?

You have decided to grind LeetCode for interviews. Great. Now you Google "best LeetCode study list" and find three options that everyone recommends:

• Blind 75 — The original 75-problem list
• NeetCode 150 — An expanded 150-problem roadmap
• LeetCode 75 — LeetCode's own curated 75 problems

Which one should you follow? The answer depends on your timeline, experience, and where you are interviewing.

Created by Yangshun Tay (ex-Meta engineer), Blind 75 is the list that started it all. It was originally posted on the anonymous tech forum Blind as "the 75 questions you need to solve to be ready for any FAANG interview."

Strengths:

• Battle-tested by thousands of engineers who landed FAANG offers
• Covers all major patterns: arrays, trees, graphs, DP, backtracking
• Compact enough to finish in 4-6 weeks at 2-3 problems per day
• Every problem is a "must-know" — no filler

Weaknesses:

• Skips some important patterns (monotonic stack, trie, union find)
• Problem selection assumes some prior experience — not ideal for complete beginners
• No official video explanations (community solutions only)

Best for: Experienced developers with 4-6 weeks until their interview. If you already know basic data structures and just need to drill patterns, Blind 75 is the most efficient path.

NeetCode 150 is an expanded version of Blind 75, created by the popular YouTube channel NeetCode. It adds 75 more problems to fill the gaps in the original list.

Strengths:

• Covers patterns that Blind 75 misses (tries, union find, intervals, math)
• Organized by topic with a clear progression from easy to hard
• Every problem has a detailed video explanation on YouTube
• The NeetCode website has a built-in progress tracker

Weaknesses:

• 150 problems takes 8-12 weeks — too long if your interview is in 3 weeks
• Some added problems are less commonly asked than the Blind 75 core
• Can feel overwhelming for beginners

Best for: Engineers with 2-3 months of prep time who want comprehensive coverage. If you are not in a rush and want to deeply understand every pattern, NeetCode 150 is the gold standard.

LeetCode 75 is LeetCode's own curated study plan, designed as a structured introduction to their platform.

Strengths:

• Official curation by LeetCode — problems are well-maintained
• Good balance of Easy and Medium — more beginner-friendly than Blind 75
• Built-in study plan feature on LeetCode with progress tracking
• Problems are tagged with the specific skill being tested

Weaknesses:

• Less battle-tested by the community compared to Blind 75
• Some overlap with Blind 75 but not identical — choosing both can cause confusion
• Fewer Hard problems — may not fully prepare you for top-tier interviews

Best for: Beginners or career switchers who are new to LeetCode. The gentler difficulty curve makes it a better starting point than jumping straight into Blind 75.

Here is what most guides will not tell you: these lists overlap significantly. About 40 problems appear in both Blind 75 and NeetCode 150. About 30 problems appear in both Blind 75 and LeetCode 75.

This means:

• If you finish Blind 75, you have already done ~40% of NeetCode 150
• Starting with LeetCode 75, then switching to Blind 75, you will repeat ~30 problems (good for reinforcement, bad for time efficiency)

If you have less than 6 weeks: Do Blind 75. It is the most efficient use of your time. Every problem is high-signal for interviews.

If you have 2-3 months: Start with Blind 75, then continue to NeetCode 150. The first 75 build your foundation, the next 75 fill the gaps.

If you are brand new to LeetCode: Start with LeetCode 75 for 2-3 weeks to build confidence, then switch to Blind 75 for the real interview patterns.

If you are targeting a specific company: Do Blind 75 as your base, then supplement with company-tagged problems. Use a tool like LeetDaily to track your progress across all three lists simultaneously with live progress bars, and filter the Problems Explorer by company tags to find frequently asked questions.

The smartest approach is to work through one list as your primary focus while tracking your incidental progress across all three. As you solve Blind 75 problems, some of them also count toward NeetCode 150 and LeetCode 75.

LeetDaily shows your progress across all three lists in a single view — Blind 75 (52/74), NeetCode 150 (89/158), LeetCode 75 (41/75) — with one-click navigation to the next unsolved problem in each list. Set your focus area to whichever list you are prioritizing, and your Focus streak (🎯) will track your daily consistency.

No spreadsheets. No Notion templates. Just install and start solving.
