Coding interviews
The Blind 75
The Blind 75 is a curated list of 75 LeetCode problems, first posted on the Blind forum, chosen to cover the core patterns behind most coding interviews. It is popular because it trades breadth for signal: 75 well-chosen problems instead of grinding hundreds. The real question is not what is on it, but whether it is enough and how to use it.
Blind 75 vs NeetCode 150 vs Grind 75
Blind 75
75 problems
The original curated set, organised by pattern. Best for a focused pass when time is short.
NeetCode 150
150 problems
The Blind 75 plus 75 more for extra reps per pattern, with video walkthroughs. Best if you have the weeks.
Grind 75
adjustable
A newer list from the same author that lets you set your timeline and hours, then sizes the set to fit.
What is the Blind 75?
The Blind 75 is a curated list of 75 LeetCode problems, originally posted on the Blind forum by a Facebook engineer, chosen to cover the core patterns behind most coding interviews. Its whole idea is signal over volume: 75 well-picked problems instead of grinding hundreds.
Is the Blind 75 enough for FAANG?
For most new-grad and mid-level loops, the Blind 75 is enough to cover the patterns, but only if you can recognise and apply each one cold, not just recall a solution you have seen. It is a floor, not a ceiling: strong candidates use it to master the patterns, then do extra reps on their weak areas and on the problem types a specific company favours.
Blind 75 vs NeetCode 150 vs Grind 75: which should I do?
If you have a week or two, do the Blind 75. If you have a month or more, NeetCode 150 gives you more reps per pattern and video explanations. Grind 75, from the same author as the original, lets you set your available hours and builds the list to match. They overlap heavily; the choice is really how much time you have.
Is the Blind 75 still relevant in 2026?
Yes. The patterns it teaches, two pointers, sliding window, graphs, dynamic programming, are the same ones interviews still test, and they do not go stale. What has changed is that top companies increasingly reuse their own tagged problems, so the Blind 75 is best paired with company-specific practice rather than used alone.
How long does the Blind 75 take?
Plan on three to six weeks at a realistic pace: a handful of problems a day, with time to redo the ones that did not click. Racing through it once to tick 75 boxes is the common mistake; the value is in being able to re-derive each pattern under pressure, which takes repetition.
Learn the patterns, not the 75 answers
The Blind 75 is a problem set, not a curriculum. It shows you the patterns exist; it does not teach the reasoning that makes an unseen problem recognisable in the first ninety seconds. That is the gap our Data Structures & Algorithms course fills, one pattern at a time, and the company guides tell you which patterns a specific company reuses most: Google leans on graphs and dynamic programming, Amazon on practical, scalable code, and Meta on arrays and hashing under a tight clock.
