After 6 months of rejections, I realized my problem wasn't coding skills - it was explaining my thought process. The detailed explanations here taught me how to articulate my answers. Just accepted an offer at Revolut with a 60% salary bump.

Meet the Founder

My name is Slawomir Plamowski (Slawek, for short). I'm a Senior Software Engineer with 15+ years of experience building large-scale enterprise systems at investment banks in EU and Switzerland.

Throughout my career, I've been on both sides of the interview table—many times. I was responsible for conducting technical interviews and onboarding new team members.

In the beginning I just wanted to help my friend get through her first technical interview. What started as a friendly help, turned into flipcards.io and easyinterview.me educational sites, that I'm sure will help you just like it helped my friend.

Frequently Asked Questions

What exactly do I get with my purchase?

You get 30-day access to 800+ interview questions and answers covering JavaScript, React, Angular, Vue.js, Node.js, TypeScript, Git, SQL, Java, and more. Each question includes detailed explanations with code examples - not just the answer, but the "why" behind it so you can confidently explain concepts in interviews.

Who created these questions?

The questions are curated by Slawomir Plamowski, a Senior Software Engineer with 15+ years of experience at investment banks in the EU and Switzerland. He's been on both sides of the interview table - conducting technical interviews and helping developers prepare. These are real questions from real interviews.

How is this different from free resources like LeetCode or YouTube?

Free resources are scattered, inconsistent, and often outdated. You spend hours searching instead of learning. EasyInterview gives you structured, curated content organized by technology and difficulty level. Every question has been verified and includes detailed explanations - no guessing if the answer is correct.

Is 30 days enough to prepare?

Absolutely. Most developers who use EasyInterview feel interview-ready within 1-2 weeks of focused practice. The questions are organized by topic and frequency, so you can prioritize what matters most. If you have an interview in 3 days, you can focus on the most commonly asked questions first.

What difficulty levels do you cover?

We cover everything from junior to senior level positions. Questions are organized by complexity - start with fundamentals and progress to advanced topics like performance optimization, design patterns, and system architecture. Whether you're preparing for your first dev job or aiming for a FAANG senior role, you'll find relevant content.

Can I try before I buy?

Yes! We offer a free preview with sample questions so you can see the quality and format before purchasing. Check out our React Interview Questions Preview to get a feel for what's included.

How do I access the questions after purchase?

Immediately after purchase, you'll receive an email with login instructions. Simply go to our online portal, log in with the email you used to purchase, and start practicing. No downloads, no apps - just instant browser access on any device.

Can I access on mobile?

Yes! The platform is fully responsive and works on phones, tablets, and desktops. Study on your commute, during lunch breaks, or wherever you have a few minutes to practice.

What if I need more time after 30 days?

You can simply purchase another 30-day access period whenever you need it. Many developers come back before their next interview cycle to refresh their knowledge.

Is the payment secure?

Absolutely. We use Shopify's secure checkout, which is trusted by millions of businesses worldwide. Your payment information is encrypted and never stored on our servers. We accept all major credit cards and PayPal.

Your Interview Is Coming Up

Most developers wait until the last minute to prepare. They scramble through random blog posts, watch 3-hour YouTube videos at 2x speed, and hope they don't get asked about closures.

Don't be that developer.

With EasyInterview, you'll be interview-ready in days, not weeks. Our questions are organized by topic, sorted by frequency, and explained in a way that actually makes sense.
