Blog / How to Pass Data Structures & Algorithms Interviews in 2026

Data Structures & Algorithms (DSA) interviews are annoying.They are a necessary evil to land a job at your favorite company.If you want to minimize the time you spend grinding DSA questions, commit to this 2-step framework.

1. The Blind 75 (The Foundation)

The Blind 75 is a collection of DSA questions curated by an ex-Meta Staff Engineer. It covers the core patterns that make up 90% of interview questions.Instead of solving random problems, this list forces you to master specific categories:

Why this matters: Studying these fundamentals ensures you recognize the type of question an interviewer is asking, rather than not knowing where to start.

2. The TechPrep 100 (The Reality)

Bad news. Studying the Blind 75 alone isn’t enough.The Blind 75 is great for concepts, but it doesn't represent the specific questions companies are asking right now.You need the TechPrep 100.We curated the top 100 questions currently trending in real interview loops at top tier companies. These are verified by external sources and are the exact questions that helped me land offers from Amazon, Stripe, and Palantir.

The Result

By combining these two lists, you become bulletproof:

Blind 75: You know how to solve the patterns.
TechPrep 100: You have practiced the actual questions they are likely to ask.

Because you have studied 175 targeted questions, nothing will surprise you. Even if they ask a question you haven't seen, it will be similar to a pattern you already know.
