InterviewAI (Eightfold Interview): AI Mock Interview Platform

Overview

InterviewAI is an AI-powered mock interview platform built with Next.js App Router, Supabase, Vapi, and Groq. It helps users practice interviews through voice-based sessions and review structured interview outcomes.

What Users Can Do

• Sign in and access dashboard: Use a combined auth flow backed by Supabase Auth.
• Start interviews: Run mock interviews through a voice-first workflow.
• Review interview history: Browse completed sessions with structured Q&A summaries.
• Explore jobs: Use a job marketplace tab with a guided pre-selection flow.

Why I built this

I built this platform to solve a practical interview prep gap:

• Practice tools are often generic and do not simulate realistic interaction patterns.
• It is difficult to track progress when feedback and transcript summaries are not structured.

Tech Stack

• Next.js
• TypeScript
• React
• Tailwind CSS
• shadcn/ui
• Supabase (Auth + Postgres)
• Vapi
• Groq

After launch & Impact

• Delivered an end-to-end interview practice workflow from login to voice session completion.
• Added structured summary generation and persistent interview history for progress tracking.
• Improved reliability with fallback behavior when Vapi or Groq keys are not configured.
• Strengthened full-stack experience in AI-assisted workflows and Supabase-backed product development.

Future Plans

• Add richer feedback analytics and trend tracking across multiple interview sessions.
• Expand role and company-specific interview packs.
• Introduce adaptive interview difficulty based on previous performance.
• Add collaborative review mode for mentor or peer feedback.
