Frequently asked questions
The short answers on how Preterview works, and a few interview-prep basics.
Preterview
What is Preterview?
Preterview is a voice mock-interview service with three AI interviewers, alongside a resume builder and a portfolio review. It's a place for developers and job seekers to rehearse their answers before the real interview.
What can I use for free?
Signing up gives you one free mock interview (valid 30 days) and one free portfolio review per account. Resume polishing is free up to 10 times a day and resume import up to 3 times a month. No credit card to start.
How does pricing work — is it a subscription?
There's no subscription. You buy interview passes only when you need them. A single pass is ₩9,900, five passes ₩29,000, and a 20-pass season pass ₩79,000; a 3-use portfolio-review pack is ₩4,900. Purchased passes are valid for 90 days.
What does one interview pass cover?
One pass equals one AI mock interview, which includes up to 24 question-and-answer turns and up to 3 report generations for that interview.
Does the AI result guarantee I'll pass?
No. The AI's questions, evaluations, and reports are there to support practice, not to guarantee an outcome. Use them as a tool to tighten the form and delivery of your answers.
Can I get a refund?
A pass you haven't used is fully refundable within 7 days of purchase. If you've used part of it, we deduct the list price for the passes used and refund the rest. The refund policy page has the full terms.
Interview prep
How is an AI mock interview different from a real one?
The biggest difference is you can answer the same question as many times as you want. On the other hand, room nerves and improvised follow-ups are hard to reproduce, so drill the basics with AI and add practice with a real person for the live feel.
How long should a 1-minute self-introduction be?
At a comfortable pace, about 130-150 words, or roughly 5-7 sentences. Write it out, time yourself reading it aloud, and aim to land between 55 seconds and just over a minute.
How should I structure an interview answer?
Use STAR — Situation, Task, Action, Result — so the listener doesn't lose the thread. Lead with your conclusion, put a number in the result where you can, and keep each answer to about 30-60 seconds.
How long should a developer resume be?
One page for new grads and juniors, and rarely more than two even for experienced candidates. Rather than padding length, drop weaker entries to raise the density of what remains.
