I Built an AI Interview Assistant That Costs $0 to Start — Here's Why

I spent months watching people fail interviews — not because they weren't smart, but because they didn't have time to practice. So I built Interview Buddy — an AI-powered interview assistant that helps you ace technical interviews, coding challenges, aptitude tests, and even proctored exams. And it starts at $0. Here's something the tech industry doesn't like to admit: Getting a job has become a test of test-taking, not talent. You might be a brilliant developer. You've shipped production code. You've debugged gnarly issues at 2am. But then you sit down for a 90-minute online assessment with trick MCQs and a timer ticking down... and you freeze. The hiring pipeline in 2026 looks like this: Most people get eliminated at step 2 — before a human even looks at them. Interview Buddy runs alongside your interview or assessment and provides real-time AI assistance: 📸 Screenshot your screen → get instant answers 🧠 MCQ support — handles aptitude, logic, and domain questions 💻 Coding challenges — multi-language support with explanations 🔒 Proctored exam mode — works invisibly alongside monitoring software 📊 Assessment prep — Turing, TestGorilla, Crossover, HackerRank, and more It's not about cheating. It's about leveling the playing field. When companies use AI to screen you out, why shouldn't you use AI to prepare better? There's a well-known competitor that charges $299/month for similar functionality. Let me be honest about the differences: For most job seekers — especially those in emerging markets where $299/month is 2-3 months' salary — Interview Buddy is a no-brainer. I'm based in Kenya, and I built this for people like me. People who are incredibly talented but get filtered out by algorithms before getting a chance to show what they can do. In Africa alone, there are millions of developers competing for remote positions on platforms like Turing, Toptal, and Crossover. The assessments are tough, proctored, and designed to eliminate — not evaluate. Interview Buddy gives these developers a fighting chance. For the developers reading this, here's what powers Interview Buddy: We're actively building: You get 5 free credits when you sign up. No credit card required. If you're currently job hunting, preparing for assessments, or know someone who is — give it a shot. And if you're a developer who wants to contribute or has feedback, I'm all ears.
