101 Must‑Read Blog Posts to Master Coding Interviews

If you’ve ever stared at a whiteboard question and felt the knot in your stomach tighten, you’re not alone. Coding interviews have become the gatekeepers of most tech jobs, and the pressure to perform can be…well, a little overwhelming.

That’s why I put together this mega‑list of 101 blog posts that actually help. The posts aren’t just random picks; they’re sorted by how much HackerNoon readers have engaged with them, so you’re getting the crowd‑approved gems first.

You can also swing by LearnRepo.com for the same curated feed across any technology you care about. Think of it as a constantly refreshed reading list, tailored by the community.

1. 14 Patterns to Ace Any Coding Interview Question – The author walks you through recurring solution shapes, from sliding windows to two‑pointer tricks, making it easier to spot the “right” approach when a brand‑new problem shows up.

2. 50+ Data Structure and Algorithms Interview Questions for Programmers – A solid grab‑bag of classic DSA puzzles, plus a few brain‑teasers like swapping two integers without a temp variable (yes, they still ask that).

3. Top 10 System Design Interview Questions for Software Engineers – System design feels like a whole other beast, but these ten questions break it down into digestible scenarios you can rehearse out loud.

4. Implementing a Singly or Doubly Linked List in Java (A LeetCode Question) – A hands‑on implementation guide that lets you see the trade‑offs between the two list flavors while you code.

5. How to Find the Product of All Elements in an Array Except Self – Blind 75 LeetCode – Learn the O(n) solution that avoids division, a favorite for interviewers who love “gotchas”.

6. The Top 10 Object‑Oriented Design Interview Questions Developers Should Know – Sprinkled with anecdotes from interviews at Facebook and Microsoft, this post shows why SOLID matters when you’re on the hot seat.

7. My Terrible Experience Applying for a Job at Crossover for Work – A candid look at one company’s hiring process, complete with red‑flags you’ll want to keep in mind when evaluating offers.

10. Comparing Coding Platforms: LeetCode, CodeWars, CodeSignal, and HackerRank – A no‑fluff rundown of the major practice sites, helping you pick the one that matches your learning style.

And that’s just the tip of the iceberg. The full collection continues with deep dives on JavaScript pitfalls, back‑tracking patterns, FAANG system‑design prep, competitive programming hacks, and even a quirky look at the “best line of code you ever wrote”. Each article is written by practitioners who’ve been on the other side of the interview table, so the advice feels grounded—not theoretical.

Bottom line: grab the list, start ticking off articles that match the gaps in your knowledge, and remember to actually write the code while you read. It’s the combination of theory and practice that turns nervous candidates into confident engineers.
