AI Interviewer
An AI-powered interviewer that conducts structured, adaptive, and unbiased interviews at scale. It responds to candidate answers dynamically, asks intelligent follow-ups, profiles coding competencies, and grades responses based on rubric constraints.
Launch Specifications
Product Overview
AI Interviewer conducts technical evaluations asynchronously. It replaces standard coding tests with a conversational, interactive system that acts like a human developer, testing boundary cases and asking candidate developers to justify their choices.
- Dynamic question paths adapting to answers.
- Interactive syntax highlighting code editor.
- Automatic rubric grading & structural logs.
- Behavioral sentiment verification.
What AI Interviewer Can Generate
Asks candidates to explain complex code lines.
Validates code compilations dynamically.
Verifies visual attention and tab focus.
Detailed breakdown of scoring points.
The Problem
Technical recruiting teams waste hundreds of hours screening candidates who copy-paste solutions. Conversely, standard linear coding puzzles fail to capture true system engineering and problem-solving skills.
Our Solution
An adaptive interview agent that doesn't just look for correct syntax, but actively probes code efficiency, testing for edge cases and forcing candidate interaction to verify reasoning depth.
Technical Architecture
The system is built on LangChain with an Express/Next.js client-facing UI. A stateful execution graph manages query cycles. Code inputs are compiled in an isolated Docker container, returning console output directly back into the LLM context loop.

Key Engineering Challenges
- •Securing user-submitted code executions inside isolated, resource-capped sandboxes.
- •Keeping follow-up prompts conversational while adhering strictly to rubric guidelines.
- •Supporting low-latency audio inputs for conversational-style voice interviews.
Key Lessons Learned
- ✓Strict system-prompt guards are necessary to stop candidates jailbreaking the rubric scoring.
- ✓Pre-compiling base code definitions reduces generation latencies by 1.2s.
- ✓Interviews must be capped at 45 minutes to prevent LLM context-window decay.
