Blind 75 LeetCode: Is it still worth your time?

If you’ve ever started prepping for coding interviews, chances are you’ve come across the Blind 75 LeetCode list. It’s a curated set of 75 problems compiled by a former Meta engineer and widely shared as one of the most efficient ways to prepare for technical interviews. 

But with so many alternatives out there now, many candidates wonder: Is Blind 75 LeetCode still worth your time in this current timeline?

Let’s dig into what makes the Blind 75 so popular, how it holds up today, and whether it fits your interview prep strategy.

What is Blind 75 LeetCode?#

Blind 75 LeetCode is a carefully selected set of 75 coding problems that cover the most common data structures and algorithm topics tested in technical interviews. These questions were originally posted on Blind, the anonymous tech community forum, and quickly gained popularity for their simplicity and effectiveness.

The list is split across common categories like:

• Arrays & Strings

• Linked Lists

• Trees

• Graphs

• Dynamic Programming

• Backtracking

• Stacks & Queues

Each problem is representative of the kinds of patterns companies like Google, Meta, and Amazon test for, making the list a go-to resource for anyone preparing for interviews at top tech companies.

Why Blind 75 LeetCode gained traction#

The appeal of Blind 75 LeetCode lies in its focus and minimalism. Instead of sifting through thousands of LeetCode questions, candidates can zero in on the 75 problems that matter most. Here’s why it became so widely adopted:

• Time-efficient: You can cover all 75 in 6–8 weeks with consistent effort.

• Pattern recognition: Builds strong intuition for core problem-solving techniques that frequently appear across interviews.

• No decision fatigue: Removes the overwhelming feeling of choosing from thousands of questions.

• Community-backed: Thousands of developers, from students to professionals, have recommended and successfully used the list.

This list gives you clarity, momentum, and confidence—all essential in interview prep.

What’s changed in 2025?#

While the core problems in Blind 75 are still relevant, the interview landscape has evolved significantly:

• New tools: NeetCode 75 offers better curation, guided video explanations, and a more structured learning experience.

• System Design and behavioral interviews now carry equal weight in mid- to senior-level interviews.

• AI-based coding platforms like CodeSignal and Codility influence how early technical assessments are conducted.

• Companies are increasingly favoring applied problem-solving over pure algorithmic puzzles.

This means candidates need to go beyond algorithms to succeed, but Blind 75 still plays an important foundational role.

Who should still use Blind 75 LeetCode?#

Blind 75 is especially useful for:

• First-time interviewees or new grads looking for a structured entry point.

• Bootcamp graduates who want a high-impact way to reinforce core topics.

• Engineers returning to the job market after a break.

• Professionals looking to ramp up DSA fundamentals quickly.

If you’re targeting companies that rely heavily on algorithmic questions, like Big Tech, quant firms, or competitive startups, this list will serve you well.

When to look beyond Blind 75#

Once you’ve solved the Blind 75 problems and built fluency in common patterns, you might need to broaden your focus:

• Senior-level roles often include System Design, architecture, and scalability trade-offs.

• Behavioral interviews require STAR-format storytelling, which is missing from algorithm-focused prep.

• Domain-specific interviews (e.g., backend, front-end, ML) often involve real-world scenario questions.

In these cases, Blind 75 is your starting platform, not the full journey.

How to make the most of Blind 75#

Here are strategies to help you extract maximum value:

• Solve with intent: Focus on the “why” behind each approach, not just getting to a working solution.

• Document learnings: Write down brute-force vs. optimal strategies, edge cases, and refactorings.

• Teach back: Explain problems and solutions to a peer or via a blog to reinforce your understanding.

• Mock interviews: Regularly simulate interview conditions with a friend or platform.

The deeper your learning process, the more reusable your insights will be in future interviews.

How to combine Blind 75 with other resources#

Here’s how to build a blended prep strategy:

• Pair Blind 75 with NeetCode or AlgoExpert for alternative solutions and visual explanations.

• Use LeetCode Discuss to read through top-rated community answers and optimizations.

• Add one System Design or behavioral question for every 3–5 Blind 75 problems.

• Create a Notion or Excel tracker that includes links to walkthroughs and notes.

This cross-pollination leads to deeper learning and higher retention.

Blind 75 as a time-boxed sprint#

If you’re under a deadline (say 4–6 weeks before interviews), use Blind 75 as a focused sprint:

• Break the list into weekly topic goals (e.g., Arrays Week, Trees Week).

• Track confidence levels (low, medium, high) rather than binary “done/not done.”

• Reserve the last week for revisiting the toughest problems and doing mocks.

This method avoids burnout and ensures breadth + depth across categories.

Mistakes to avoid with Blind 75#

Even a great list can be misused. Avoid these traps:

• Grinding without reflection: Speed without insight won't help in interviews.

• Rote memorization: Understanding the why is more important than recall.

• Ignoring context: Interviewers care about real-world applicability—bring up trade-offs and scalability.

• Skipping walkthroughs: Videos and top solutions often reveal hidden edge cases and clever optimizations.

Being deliberate with your approach improves learning quality, not just quantity.

How hiring managers view Blind 75-style prep#

Hiring managers can often tell when candidates have done focused problem sets like Blind 75. They appreciate:

• Familiarity with common problem patterns

• Clean, modular code with thoughtful variable names

• Articulation of edge cases, test strategies, and trade-offs

However, they’ll also probe beyond templated answers—so your explanations and adaptability matter just as much.

How Blind 75 helps with pattern recognition#

The real magic of Blind 75 is in the patterns it teaches. After a few weeks of practice:

• You begin to see that many problems are variants of the same core idea.

• You improve your ability to choose the right data structure from the start.

• You learn how to recognize brute-force approaches—and avoid them when possible.

This pattern fluency reduces interview-day anxiety and boosts problem-solving confidence.

Incorporating Blind 75 into a long-term strategy#

To go beyond the interview grind:

• Use Blind 75 as the base layer in your technical fluency.

• Build side projects or contribute to open source to apply DSA in real-world systems.

• Pair Blind 75 with System Design courses or mock interview prep as you advance.

Long-term success isn’t just about passing interviews—it’s about becoming a well-rounded, high-impact engineer.

Final thoughts#

Blind 75 LeetCode is still worth your time, especially if you’re just starting out or need a focused way to build algorithmic confidence. It won’t cover everything (like System Design or behavioral strategy), but it remains one of the highest-impact tools in early interview prep.

Think of it as your algorithmic bootcamp. Once you’ve mastered it, you’ll be ready to branch into deeper topics with more context and confidence.

So, is it still worth it? Absolutely—as long as you treat it as the beginning, not the end, of your interview prep roadmap.
