Inspiration

PrepWise was born out of a common but persistent frustration: preparing for interviews often feels overwhelming, unpredictable, and lonely. As early-career professionals ourselves, we noticed that while there are plenty of career resources, few actually help you practice, get real feedback, and build confidence for the real thing. Inspired by advances in AI and the power of collective learning, we realized that with the right technology, anyone could walk into an interview ready, resilient, and one step ahead.

What it does

PrepWise is an AI-powered interview coach that helps early-career professionals prepare for interviews with confidence and strategy. Here’s how it works:

Personalized Mock Interviews: Tell PrepWise your target role or company, and it simulates recruiter and hiring manager dynamics tailored to your goals.

Nuanced Feedback: Get actionable insights on your storytelling, presence, and how well your responses align with the job.

Real-World Question Bank: PrepWise learns from real user experiences via Glassdoor, surfacing the latest questions asked by top employers in your field.

Growth Tracking: The platform remembers your progress, highlights improvements, and flags areas for further practice.

Confidence Building: Access guided exercises to manage anxiety and build presence before your big day.

With PrepWise, you’re never practicing alone—you’re tapping into a shared intelligence network that gets smarter with every user and every question.

How we built it

Data Foundation with Apify We scraped 250,000+ interview experiences from Glassdoor using Apify’s configurable scraper , capturing behavioral questions, technical challenges, and company culture insights across industries.

Voice Realism via Leaping.ai Integrated Leaping.ai’s no-code voice platform to simulate recruiter interactions with <2s latency, handling complex dialogue trees and emotional tonality.

AI Analysis with OpenAI GPT-4o powers our feedback engine, evaluating responses against 5+ competency frameworks (e.g., STAR method, technical depth) and suggesting improvements.

Rapid Prototyping on bolt.new Leveraged bolt.new’s browser-based IDE to build and deploy PrepWise without local environments, using its token system to optimize AI resource allocation during peak usage.

Challenges we ran into

No Direct Glassdoor API Access Glassdoor’s public API was discontinued in 2021, forcing us to use Apify’s Glassdoor Jobs Scraper as a workaround. Apify provided reliable data extraction.

Phone-Based Mock Interviews Without a web interface, we relied on outbound call simulations for mock interviews. This introduced: -Inability to assess visual cues like body language -Technical constraints with call quality and recording analysis

Accomplishments that we're proud of

Seamless Voice + AI Workflow: Combining Leaping.ai’s autonomous agents with GPT-4o’s analysis created end-to-end prep cycles that feel human yet scale infinitely.

Real-Time Data Advantage: Apify’s scraper updates our question bank daily, ensuring users practice with the latest trends from top employers like Google and McKinsey.

Cost-Efficient Scaling: bolt.new’s token system let us deploy high-quality mock interviews at 1/3 the cloud cost of traditional infrastructure.

What we learned

What's next for PrepWise

Multi-Modal Interviews: Add video analysis via ChatGPT’s vision capabilities to critique body language and slide decks.

Enterprise Scaling: Expand Leaping.ai integrations for corporate training programs handling 100k+ annual interviews.

Self-Improving Agents: Implement bolt.new’s incremental deployment to let users A/B test interview strategies in real-time.

By merging cutting-edge tools with real-world insights, PrepWise is redefining how early-career professionals turn interviews into opportunities. 🚀
