TL;DR

Is NeetCode 150 enough? For learning the patterns, yes. For passing a specific company’s interview, it depends. We checked NeetCode 150 against 1,500+ real interview questions and found it directly covers 29-39% of what FAANG companies actually ask. The patterns transfer beyond those exact problems, but you need to know your target company’s topic bias. Google hammers graphs and trees. Amazon and Microsoft lean heavily on backtracking. Apple obsesses over BSTs. NeetCode 150 gives you the foundation. Company-specific practice closes the gap.

The Data: 1,500+ Real Interview Questions

Most articles answering “is NeetCode 150 enough” are opinion pieces. They say things like “it covers 70-80% of patterns” without citing a source. We wanted actual numbers.

We built a database of 1,837 real interview problems collected from 459 companies. Each problem is tagged with the company that asked it, the topic category, and the difficulty level. We then mapped every NeetCode 150 problem against this database by LeetCode slug to get exact coverage percentages per company.

The results surprised us. NeetCode 150 is not a “solve these and you will pass anything” list. It is a pattern-building list that covers a specific slice of what each company tests.

FAANG Coverage Breakdown

37% direct coverage does not mean you only know 37% of the answers. NeetCode 150 teaches patterns, not just specific problems. If you deeply understand the sliding window pattern from NeetCode 150, you can solve most sliding window problems you encounter, even ones not in the list. The real coverage is higher than the direct-match percentage suggests.

But the numbers reveal something critical: coverage varies dramatically by company. Amazon at 39% and Google at 29% is a 10 percentage point gap. If you are preparing the same way for both, you are wasting time on one and underexposed for the other.

Topic Multipliers: What Each Company Actually Tests

Coverage percentage only tells part of the story. The real insight is in the topic multipliers: how much more (or less) a company tests a specific topic compared to the global average across all 459 companies.

A multiplier of 16.4x means that company asks that topic 16.4 times more often than the average company. These biases are where NeetCode 150 either saves you or leaves you blind.

Microsoft

Multiplier = how much more a company tests this topic vs. the global average

The pattern is clear. Amazon, Microsoft, and Meta all hammer backtracking at 15-16x the global average. NeetCode 150 has 9 backtracking problems, which is actually good coverage for this pattern. If you are targeting any of these three, your backtracking needs to be sharp.

Google and Apple lean toward trees and graphs. Google tests trees at 7.6x and graphs at 6.8x the average. Apple tests BSTs at 4.5x. NeetCode 150 has 15 tree problems and 19 graph problems, which gives you solid fundamentals, but Google’s graph problems tend to be more advanced than what NeetCode covers.

What NeetCode 150 Does Not Cover

NeetCode 150 is a DSA list. It explicitly does not cover three major components of FAANG interviews:

architectureSystem Design

Every FAANG interview loop includes at least one system design round. NeetCode 150 does not touch this. You need separate preparation for designing distributed systems, database schemas, and API architectures.

psychologyBehavioral Interviews

Amazon has 14 leadership principles. Meta asks about conflict resolution. Google probes for Googleyness. These rounds are pass/fail gates that NeetCode 150 cannot prepare you for.

databaseSQL and Data Problems

Some companies (especially for data-adjacent roles) include SQL rounds or data manipulation problems. NeetCode 150 is purely algorithmic and has no SQL coverage.

This is not a criticism of NeetCode 150. It was designed for coding rounds specifically, and it does that job well. But if you think completing NeetCode 150 means you are “ready for FAANG,” you are missing at least half the interview loop.

Company-by-Company: Is NeetCode 150 Enough?

Google (29% coverage)

Google has the lowest NeetCode 150 coverage of any FAANG company. They test graphs at 6.8x and trees at 7.6x the global average. NeetCode 150 gives you good graph and tree fundamentals, but Google’s graph problems tend to involve advanced techniques like modified Dijkstra, complex BFS with state, and custom graph modeling that goes beyond the standard NeetCode problems.

Verdict: NeetCode 150 is necessary but not sufficient. After completing it, supplement with 20-30 Google-tagged problems focusing on advanced graphs and tree manipulation.

Amazon (39% coverage)

Amazon tests backtracking at 16.4x the global average. NeetCode 150 has 9 backtracking problems (Subsets, Permutations, N-Queens, etc.), which covers the core patterns well. Amazon also tests arrays heavily, and NeetCode 150 has solid array coverage. The gap is more about volume than missing patterns.

Verdict: NeetCode 150 gets you close. After completing it, do 10-15 Amazon-tagged problems to build speed and see their specific question style.

Meta (39% coverage)

Meta tests both backtracking (15.7x) and binary trees (10.7x) heavily. NeetCode 150 covers both of these well. Meta interviews tend to favor problems that are solvable in 20-25 minutes and test clean implementation over complex algorithms. The NeetCode 150 Medium problems align well with this style.

Verdict: NeetCode 150 is a good match for Meta’s coding rounds. Supplement with Meta-tagged problems to learn their pacing and preferred problem types.

Apple (38% coverage)

Apple has a BST obsession: 4.5x the global average. They also test binary trees at 10.1x. NeetCode 150 has 15 tree problems and covers BST operations well (Validate BST, Kth Smallest, LCA). Apple interviews skew easier than Google, with 62% Medium and only 15% Hard.

Verdict: NeetCode 150 is enough for the coding rounds if you make trees your strongest topic. Their difficulty level matches NeetCode’s Medium problems well.

Microsoft (39% coverage)

Microsoft mirrors Amazon’s pattern with backtracking at 16.5x. They also test trees at 4.2x and arrays at 3.5x. NeetCode 150 covers all three topics well. Microsoft interviews are generally considered slightly more structured and slightly easier than Google’s.

Verdict: NeetCode 150 plus 10-15 Microsoft-tagged problems is solid preparation. Focus your supplementary practice on backtracking and tree problems.

The Verdict

Is NeetCode 150 enough? For learning DSA patterns, yes. For passing a specific company’s coding interview, it is a strong foundation that covers roughly a third of what you will face, plus transferable patterns that extend your effective coverage much higher.

The optimal strategy is not “do NeetCode 150 and stop.” It is:

1

Complete NeetCode 150 to build your pattern foundation across all 16 categories.

2

Check your target company's topic multipliers to see where they test hardest.

3

Do 15-30 company-tagged problems in those high-multiplier topics.

4

Practice under interview conditions with timed mock interviews.

Use our NeetCode 150 study planner to build your schedule, then check your target company on our company interview questions page to see exactly what they ask. When you are ready, try a free AI mock interview to test yourself under pressure.

Frequently Asked Questions

Is NeetCode 150 enough for Google interviews?expand_more

NeetCode 150 covers about 29% of the problems Google actually asks, based on our analysis of real interview questions. Google tests graphs and trees at 7-8x the global average. NeetCode 150 has 19 graph and 15 tree problems, which is a reasonable foundation, but you will need additional practice with advanced graph algorithms like Dijkstra variants and complex tree manipulation to be fully prepared.

Is NeetCode 150 enough for Amazon interviews?expand_more

NeetCode 150 covers about 39% of the problems Amazon asks. Amazon tests backtracking at 16.4x the global average and arrays heavily. NeetCode 150 has 9 backtracking problems which provides good pattern coverage, but you should supplement with Amazon-specific practice on their most-asked topics using company-tagged questions.

How long does it take to complete NeetCode 150?expand_more

NeetCode 150 takes roughly 85-100 hours of focused practice, or about 6-8 weeks at 2 hours per day. This includes time for understanding solutions, not just coding them. If you are new to DSA, expect closer to 10-12 weeks as you will need more time on unfamiliar patterns like dynamic programming and graph algorithms.

Should I do NeetCode 150 or study company-tagged questions?expand_more

Do both, in that order. NeetCode 150 builds your pattern foundation across all major algorithm categories. Company-tagged questions show you which patterns your specific target company emphasizes. Without the NeetCode 150 foundation, company-tagged questions are much harder to learn from. Without company-tagged questions, you may over-prepare in areas your target company rarely tests.

What does NeetCode 150 not cover?expand_more

NeetCode 150 focuses exclusively on data structures and algorithms. It does not cover system design interviews, behavioral interviews, object-oriented design, or SQL/database questions. Most FAANG interview loops include at least one system design round and one behavioral round alongside the coding rounds. You will need separate preparation for those.
