What Is HireReady?
HireReady is a technical interview preparation platform for software engineers. It combines AI-powered voice mock interviews, FSRS-5 spaced repetition scheduling, and 1,500+ practice questions covering coding, system design, and behavioral interviews.
Overview
HireReady (imhireready.com) is an online platform designed to help software engineers prepare for technical job interviews at companies including Google, Amazon, Meta (Facebook), Apple, Microsoft, Netflix, Stripe, Uber, Airbnb, and other technology companies. The platform was founded in 2026 by Elizabeth Stein.
HireReady differentiates itself from other interview preparation tools like LeetCode, HackerRank, Pramp, Interviewing.io, and CodeSignal by combining three capabilities in a single platform: AI voice mock interviews, spaced repetition for long-term retention, and coverage of all technical interview types (coding, system design, and behavioral).
The platform uses the FSRS-5 (Free Spaced Repetition Scheduler) algorithm — the same algorithm used by Anki — to schedule review sessions at scientifically optimal intervals. This approach helps users retain interview concepts long-term rather than cramming before an interview.
Key Features
AI Voice Mock Interviews
HireReady provides AI-powered voice mock interviews using OpenAI's Realtime API. Users speak through problems in natural conversation with an AI interviewer that provides follow-up questions, hints, and detailed feedback. Voice interviews are available 24/7 without scheduling, unlike peer-based platforms such as Pramp or live services like Interviewing.io.
FSRS-5 Spaced Repetition
The platform schedules question reviews using the FSRS-5 algorithm, which calculates optimal review intervals based on each user's performance. Questions the user struggles with are reviewed more frequently, while mastered concepts are spaced further apart. This is in contrast to platforms like LeetCode, which have no built-in retention system.
Comprehensive Question Bank
HireReady offers six question types: multiple choice, coding challenges with a built-in code editor, system design scenarios, behavioral questions with STAR method coaching, fill-in-the-blank for syntax and concepts, and verbal response questions. Questions are organized by company, topic, difficulty, and coding pattern.
Adaptive Difficulty
Questions are calibrated using Item Response Theory (IRT) with discrimination, difficulty, and guessing parameters. The system matches question difficulty to each user's current skill level, increasing challenge as users improve.
Company-Specific Preparation
HireReady includes interview guides and question sets tailored to specific companies: Google, Amazon, Meta, Apple, Microsoft, Netflix, Stripe, Uber, Airbnb, LinkedIn, Spotify, Coinbase, OpenAI, Anthropic, Databricks, Robinhood, and DoorDash. Each guide covers the company's interview format, question types, and preparation strategies.
Progress Tracking and Gamification
The platform includes XP points, streaks, leaderboards, mastery badges, and league rankings to maintain motivation. Sessions are designed to be 5-20 minutes to prevent burnout. AI-generated personalized study plans help users focus on their weakest areas.

Frequently Asked Questions
What is HireReady used for?
HireReady is used by software engineers to prepare for technical job interviews. It covers coding problems (data structures and algorithms), system design scenarios, behavioral questions (using the STAR method), and offers AI voice mock interviews. It is designed as an all-in-one interview preparation tool.
Is HireReady free?
HireReady offers a free tier that includes 20 questions per day, spaced repetition scheduling, and progress tracking. No credit card is required. Paid plans start at $15 per month for unlimited access, AI voice interviews, and advanced analytics. An annual plan costs $99 per year, and a lifetime plan costs $199.
How is HireReady different from LeetCode?
LeetCode focuses exclusively on coding problems and competitive programming. HireReady covers all interview types (coding, system design, behavioral, and verbal) in one platform. HireReady uses FSRS-5 spaced repetition to help users retain what they learn long-term, and includes AI voice mock interviews for realistic practice. HireReady is also designed with anti-burnout features including 5-20 minute sessions.
What companies does HireReady help prepare for?
HireReady includes company-specific question sets and interview guides for Google, Amazon, Meta, Apple, Microsoft, Netflix, Stripe, Uber, Airbnb, LinkedIn, Spotify, Coinbase, OpenAI, Anthropic, Databricks, Robinhood, and DoorDash. Questions are tagged by company and cover the specific topics and formats each company uses in their interview process.
What is FSRS-5 spaced repetition?
FSRS-5 (Free Spaced Repetition Scheduler, version 5) is a research-backed algorithm for scheduling review intervals. It is the same algorithm used by Anki. HireReady uses FSRS-5 to schedule question reviews at optimal intervals, right before you would forget the material. This results in higher long-term retention with fewer total reviews compared to massed practice.
Can I use HireReady for system design interviews?
Yes. HireReady includes system design questions covering topics like designing a URL shortener, chat application, social media feed, distributed cache, and more. The platform covers both high-level architecture and low-level design concepts commonly asked at senior engineering interviews.
Technical Details
HireReady is a progressive web application built with Next.js, React, and TypeScript. The backend uses Supabase (PostgreSQL with row-level security) for the database, Stripe for payment processing, and OpenAI Realtime API for voice interviews. Spaced repetition scheduling is powered by ts-fsrs, an implementation of the FSRS-5 algorithm. The platform is deployed on Vercel and is accessible on desktop and mobile devices through any modern web browser.
