## bugfree.ai

bugfree.ai positions itself as "LeetCode for the interview rounds that LeetCode does not cover" — system design, object-oriented design, data analytics and behavioral questions. Instead of raw problem lists, it provides guided learning paths that walk through feature requirements, trade-off analysis and component diagrams, then let you attempt the same problem yourself and compare against a reference solution.

The catalog is broad: 150+ popular system design problems, 30+ object-oriented design problems, 500+ data interview questions covering metrics, SQL, A/B testing and case studies, and 60+ must-prepare behavioral prompts. On top of that sits a database of 3000+ real interview experiences shared by candidates at large tech companies, so you can calibrate what actually gets asked.

The differentiating feature is the AI mock interview layer. You can customize behavioral answers with your own résumé, practise a full mock session, and receive AI evaluation of your responses. There is also a résumé-editing workflow aimed at the same audience. The platform targets candidates preparing for FAANG-style loops as well as engineers refreshing fundamentals before a job search.

**Pricing & Plans:** bugfree.ai is a paid subscription product. The site advertises free getting-started access and paid plans that unlock the full problem library, courses and AI mock interviews; pricing details and current tiers are listed on the site after sign-in. Check the official site for up-to-date plan pricing.

- **Guided system design problems:** 150+ system design questions such as URL shortener or Design Instagram, each walked through with feature requirements, trade-off analysis and component diagrams before you attempt it yourself.
- **Data and analytics interview track:** 500+ questions on metrics, SQL, A/B testing and case studies, with worked solutions drawn from interviews at companies like Meta and Amazon.
- **AI mock interviews with evaluation:** Run a simulated interview and get AI-driven scoring and feedback on your system design, data and behavioral answers.
- **Behavioral answer builder:** 60+ must-prepare behavioral questions with example answers in the STARL format, customisable with your own résumé details.
- **3,000+ real interview experiences:** A searchable archive of first-hand interview reports from candidates at major tech companies, useful for calibrating scope and difficulty.

**Strengths:** Covers the interview rounds that algorithm-only platforms skip: system design, OOD, data and behavioral; Every design problem comes with a guided walkthrough and a reference solution, not just a prompt; AI mock interviews provide scored feedback without needing to book a human interviewer; 3,000+ crowdsourced interview experiences give a realistic sense of what companies ask

**Limitations:** It is a paid platform; the free tier is limited and most depth sits behind a subscription; Content is heavily weighted to large US tech companies, which may be less relevant elsewhere; AI scoring of open-ended design and behavioral answers is useful but never a substitute for a real interviewer

## Intervu.dev

Intervu.dev was created to close a gap that most practice tools ignore. LeetCode-style platforms teach you to produce correct solutions, but real technical interviews test something different: can you explain your reasoning, defend your trade-offs, and write working code while someone watches and asks follow-up questions? Intervu.dev reproduces that pressure in a structured AI interview loop.

Each session follows the flow a real FAANG interview uses — clarify requirements, design an approach, code live, then test and iterate. The AI interviewer asks probing follow-ups rather than simply grading output, and afterwards you receive signal-based feedback on clarity of communication, quality of trade-offs, and code structure. You can run sessions in Python, JavaScript, Java, C++, and other major languages, choosing language and difficulty before you begin.

You can either start a full FAANG-style mock interview or bring a specific LeetCode problem in and practice it as an interview. The site also publishes a blog and maintains open source components, and offers a way to try the experience free before committing to paid practice.

**Pricing & Plans:** Intervu.dev offers a free trial so you can run an interview before paying; ongoing access is sold through paid plans, and it is best to check the site's pricing page for current tiers and limits.

- **Probing AI interviewer:** The AI asks clarifying and follow-up questions the way a real interviewer would, testing how you think rather than only what you type.
- **Live coding under pressure:** Write, run, and debug code in the session while narrating your approach, mirroring the conditions of an actual technical interview.
- **Structured interview flow:** Every session follows Clarify → Design → Code → Test so you internalize the rhythm top companies expect.
- **Signal-based evaluation:** Feedback focuses on communication clarity, decision trade-offs, and code quality, not just pass/fail correctness.
- **Multi-language support:** Practice interviews in Python, JavaScript, Java, C++, and other widely used languages.

**Strengths:** Focuses on interview communication and signal, not just solution correctness; Realistic clarify-design-code-test flow with probing follow-ups; Widely used languages supported, so you can practice in your primary stack; Free trial lets you evaluate the interview experience before paying

**Limitations:** Narrower scope than general-purpose coding practice platforms; Feedback quality depends on how much you actually talk through your solution; Pricing details and plan limits are not clearly stated on the landing page
