I Joined Educative’s 30-Day Coding Challenge: Here’s Why You Should Too

30-day coding challenge is to build your coding interview fitness

Hello guys, If you’ve been meaning to level up your coding skills but struggle to stay consistent, Educative’s 30-Day Coding Challenge is exactly what you need.

It’s the perfect blend of daily accountability, hands-on coding practice, and a chance to win some seriously cool prizes — including a MacBook Air, Sony WH-1000XM4 headphones, and $50 gift cards.

If Educative’ Grokking Coding Interview Pattern course was not enough, this month, Educative is turning coding practice into a game — one that rewards not just your progress but also your persistence.

Whether you’re brushing up on data structures, preparing for coding interviews, or just trying to make coding a daily habit, this challenge gives you a structured path and tangible motivation to stick with it.

How the Challenge Works?

The concept is simple but effective. Every day, Educative.io releases a new coding challenge that takes around 15 minutes to solve.

You can choose your preferred programming language — Python, Java, C++, or JavaScript — and even switch between them anytime.

But here’s the twist: you only get a limited number of attempts for each problem. That means every submission counts, and you’ll need to think critically before hitting “run.”

Each completed problem earns you tickets, and the longer your streak, the more raffle entries you collect — boosting your chances of winning the monthly prizes.

How to Earn Tickets?

You earn tickets for consistency and engagement throughout the challenge. Here’s how the point system works:

So, if you’re consistent and share your progress online, you could easily rack up dozens of tickets — and that’s before factoring in leaderboard bonuses.

A Sample Challenge: Convert Sorted Array to Binary Search Tree

Here’s an example of what you can expect from the daily problems, this was yesterday’s problem, every day you will see a new problem

Problem: Convert Sorted Array to Binary Search Tree
Difficulty: Medium
Time: ~15 minutes

You’re given a sorted array of integers and need to construct a height-balanced binary search tree (BST) from it. The left and right subtrees of any node must not differ in height by more than one.

Constraints:

  • 1 ≤ nums.length ≤ ¹⁰³
  • −¹⁰⁴ ≤ nums[i] ≤ ¹⁰⁴
  • The array is sorted in strictly ascending order.

This type of challenge is perfect for practicing recursive logic and understanding balanced tree structures — exactly the kind of problem that sharpens your interview-ready mindset.

The challenge also comes with test cases and you can run your solution right in your browser just like LeetCode

And, here is today’s problem which is slightly tougher but you can use Educative’s excellent sample feature to understand the problem better before attempting to solve it:

When you land on this page, click on the understand with Examples button or link and you will see a couple of examples of how to solve the problem to really understand it like

I am loving these new coding challenges everyday, and I highly recommend this to every developer, especially those who are preparing for coding interviews.

Why This Challenge Is Worth It?

There’s something incredibly powerful about doing a small, focused task every day and this free coding challenge is a great opportunity to do that.

By committing to just 15–20 minutes daily, you’ll gradually build the muscle memory and problem-solving intuition that separates confident developers from casual coders.

Even better, Educative’s interactive coding platform provides instant feedback, detailed explanations, and the ability to retry until you nail it — so every problem becomes a learning opportunity.

Plus, the daily streak feature keeps you motivated, gamifying consistency in a way that few platforms manage to do well.

If you are preparing for coding interviews, ,particularly FAANG+ companies then I highly recommend you to join this coding challenges, also its complete free and there are prizes to be won, if you are lucky.

My Experience So Far

After completing a few days’ worth of problems, I’ve noticed my problem-solving speed improving and my confidence in approaching new data structure challenges growing.

The problems are thoughtfully designed — not too easy, not too hard — and they align closely with what you’d face in real coding interviews.

But what really stands out is how Educative turns coding into a rewarding habit. Watching your streak grow and earning tickets for prizes makes the grind genuinely enjoyable.

I am not on leaderboard yet but hope to find my way up soon, though I am also worried that I may not last long 🙁 given all the things I try to do at the same time.

But that shouldn’t discourage you, instead you should focus and I am sure after 30-days your coding skill and confidence both will be much better and you will be definitely interview ready.

Start with this problem which is relatively easy but don’t use AI to submit solution, the game is not about winning prize but about improving your coding skills.
