Technical Highlights
Building TalentSprout required integrating cutting-edge AI technologies with scalable, real-time infrastructure to deliver seamless AI-powered interviews.
AI-Powered Voice Interview Automation
TalentSprout leverages OpenAI’s real-time voice API to conduct automated candidate screenings. The AI agent asks pre-set interview questions, transcribes responses in real time, and generates automated candidate fit scores, streamlining the hiring process.
To ensure smooth voice processing and live interaction, I implemented LiveKit for audio streaming and WebRTC-based communication. The backend analyzes voice responses for sentiment, clarity, and relevance, delivering structured interview summaries.
Scalable SaaS Architecture
TalentSprout’s backend is built with Python (FastAPI) and PostgreSQL, deployed on Vercel for rapid scaling. The system supports real-time AI processing using serverless functions, ensuring minimal latency when analyzing responses.
The platform’s Next.js frontend provides a seamless user experience, allowing recruiters to manage interviews, review insights, and export AI-generated reports. Secure authentication and role-based access controls (RBAC) were implemented to protect sensitive hiring data.
Bias Reduction & AI-Driven Candidate Scoring
To mitigate unconscious hiring bias, TalentSprout applies a structured AI scoring model, evaluating candidates based on pre-defined, objective criteria rather than subjective human judgment. AI grading is based on speech clarity, content relevance, and sentiment analysis, ensuring fair and consistent assessments.
Automated Hiring Workflow
TalentSprout streamlines the hiring process by automating the entire interview-to-assessment pipeline:1) Recruiters create interview templates → Define job-specific questions and scoring parameters.
2) Candidates receive AI interview links → Answer pre-recorded questions via voice interface.
3) AI analyzes responses & generates reports → Recruiters receive instant insights and structured candidate scores.
This automation allows HR teams to screen hundreds of candidates in minutes, drastically reducing the cost and time spent on initial interview rounds.
