What exactly is SharpSkill?

SharpSkill is a technical interview preparation platform for developers. You get 12,700+ real interview questions, flashcards, technical tests, code review exercises and interview simulators on React, Node.js, Angular, Spring Boot, Go, Rust and more than 10 technologies. The goal: understand your stack in depth and walk into interviews with confidence.

Who is it for?

For developers preparing a technical interview, whether junior, mid or senior. Whether you're looking for a first role, switching stacks or aiming for a senior promotion, SharpSkill adapts to your level and your technology.

Which technologies are covered?

Frontend (React, Vue, Angular, Next.js, Nuxt), backend (Node.js, NestJS, Spring Boot, Django, Laravel, .NET, Go, Rust, Ruby on Rails, Symfony), mobile (iOS, Android, React Native, Flutter), DevOps and data (Data Science, Data Analytics, Data Engineering). New stacks are added regularly based on user feedback.

How is it different from ChatGPT or a simple quiz?

Questions come from real technical interviews, written and validated by developers who've been through them. Unlike a chatbot that improvises generic answers, you train on verified content. Flashcards use active recall for long-term retention, code review exercises teach you to spot bugs and security flaws like in a senior interview, simulators recreate interview conditions with a timer and constraints, and progress tracking shows you exactly what's left to work on.

How much does it cost?

A free tier lets you try the platform with no commitment. Premium plans give full access to all 12,700+ questions, interview simulators and technical tests across every technology. Details are on the Plans page.

Where do the job postings come from?

From companies hiring for your stack, across 28 countries. Our collectors run every day, remove duplicates and tag every job with its technology. When a job lists a salary or a day rate, we keep it.

Can I apply directly from SharpSkill?

Yes. Each posting links to the employer's application page or to the board that published it. We don't sit between you and the company. Before you apply, the posting shows the cheatsheet and technical test modules that match its skills, so you prepare that interview, not a generic one.

What does a free account see on the job board?

The real numbers: how many jobs match your stack and your filters, and how many are new. Plus the 3 best jobs of your stack, readable in full. The other rows keep the contract, the location and the pay, but not the title or the company, and the link to apply is for subscribers.

How do I get started?

Create a free account, pick the technology you want to prepare and start with flashcards or interview questions. You can jump into the simulators as soon as you feel ready to train in real conditions.
