Why PrepTen exists
Most people don't fail interviews because they lack knowledge — they fail because they haven't practiced out loud. Reading notes feels productive, but it's nothing like the pressure of answering a real question on the spot. The problem is that good practice usually needs another person: a mentor, a senior, a friend who knows the field. That help isn't always available, especially the night before an interview.
PrepTen was built to be that practice partner — patient, available 24/7, and tuned to the exact subject or role you're preparing for.
What PrepTen does
PrepTen runs a realistic mock interview with you. You choose what you want to be tested on, the AI plays the interviewer, and at the end you get an honest scorecard that shows what you did well and what to fix. Specifically:
- You pick the focus — a student subject (Java, DBMS, Operating Systems, Networks…), a professional role (Backend Developer, Data Scientist…), an HR round, or FAQ/MAANG-style questions.
- You set the intensity — Easy, Medium, or Hard — and how long: a number of questions or a time limit.
- You answer by typing or speaking — voice input lets you rehearse like a real conversation.
- You get a detailed report — a score out of 100, your strengths, your weak spots, and a better model answer for each question.
How it works under the hood
PrepTen is powered by Google's Gemini AI, which generates fresh, context-aware questions and evaluates your answers the way a thoughtful interviewer would. The app avoids repeating questions you've already seen, adapts follow-ups to what you say, and keeps the conversation focused on your chosen topic. There's no account to create and no setup — open the site and start practicing in seconds.
Who it's for
- Students preparing for campus placements, vivas, and semester interviews.
- Job seekers getting ready for technical and HR rounds.
- Working professionals targeting a new role and wanting to sharpen their answers.
- Anyone who gets nervous in interviews and wants low-stakes reps before the real thing.
Our approach
We believe practice should be honest and affordable. The feedback doesn't flatter you — it tells you where you'd lose marks so you can fix it before it counts. And you can try it free before paying anything. PrepTen is built and maintained by Venkata Krishna, an engineer who wanted a faster, friendlier way to rehearse for interviews.
