Prepair is a practice tool for people preparing for technical interviews.
You choose a role — QA Manual, QA Automation, Java, Python, Go, Node, PHP, Ruby, C++, JavaScript, React, Vue, Angular, Next.js, iOS, Android, DevOps/SRE, Data Engineer, Business Analyst, Product, Project, Design or Marketing — and a level from Junior to Senior. An AI interviewer then asks questions the way a company would: one at a time, in your language, with no hints and no multiple choice. You answer in your own words, as you would out loud.
What makes it useful is what happens after each answer. Every response is scored and broken down: which parts of the question you actually addressed, what a stronger answer would have covered, and which topics are worth revising before the real thing. The scoring is deliberately not generous — an answer that sounds confident but says nothing gets told so, because that is the feedback a real interviewer will never give you.
A session runs 5 to 30 questions depending on your plan, and takes around half an hour. Three interviews a month are free and require no card. Paid plans add unlimited sessions, longer interviews, model answers, questions generated from a specific job posting, and answering out loud by voice.
You can try a single question with no account at all — pick a role on the homepage, answer, and see exactly how it is scored before deciding whether any of this is for you.
