# Star Interview

> Star Interview (starinterview.io) is an interview preparation app. Candidates practice their interview out loud with an AI interviewer that asks follow-up questions, then get a written report on what to fix. It also researches target companies (podcast-style company audio), turns your own experience into STAR answers (Story Bank) and writes a resume, cover letter and LinkedIn text for the role you want (Resume Studio).

This file follows the llms.txt proposal (https://llmstxt.org). It is generated from the same catalogs as the site, so the interview types, companies, guides, practice questions and prices below match the live pages. Every link is a public page that renders without signing in.

Key facts:

- Made by Pendwa LLC. Canonical site: https://staging.starinterview.io. Contact: hello@pendwa.org or https://staging.starinterview.io/contact.
- Who it is for: anyone preparing for a job interview, in tech and outside it. Each interview type below says who it suits.
- Mock interviews: 11 interview types, each a live voice conversation in the browser. The AI interviewer asks the questions of that round, follows up on your decisions, your own contribution and your results, and keeps time. A full format ends with a written report for that round: what worked, what to improve, a readiness rating (Not yet, Getting there, Ready, Strong) and stronger versions of your answers built from your own facts. Five-minute drills give shorter notes. Each format, its cost and its feedback are listed under Interview types.
- Pro includes 1 interview credit each month for any interview that costs a credit, plus 3 five-minute drills a day.
- Practice questions come from reported interviews and employer guidance. Star Interview does not promise which questions a real interviewer will ask.
- Company research: each company page brings together what the company says (careers pages, mission, values, leadership), what it is doing (engineering blogs, product news, interviews) and what candidates report (questions, stages, recurring themes). Where we have it, a page also shows the company's round formats (for example the length, levels and known questions of its system design round), with the date the sources were read. No company listed? General prep is built from research across many companies, and visitors can request a company.
- Free without an account: browsing the company library, company pages, practice questions, guides and free audio episodes. Creating an account is free.
