InterviewAI
AI-Powered Interview Preparation Platform
Interview preparation is most useful when feedback is tied to a specific role, the candidate's evidence, and the quality of each answer.
Interactive preview
Full demoWhat I Built
AI-powered interview preparation platform that analyzes resumes to generate personalized interview questions, simulates realistic timed interviews, and provides multi-dimensional performance feedback with AI-generated improvement suggestions.
Evidence
Working interface, documented system behavior, and implementation-level decisions.
Technical Architecture
From system input to explainable output.
The control gate is shown as a first-class stage, not an afterthought added around the workflow.
Technical Decisions
- Built an interview preparation platform that parses a resume, extracts skills and experience, and generates questions targeted at that specific background.
Security Considerations
- The public case study makes no additional security claim beyond the documented controls shown in the architecture.
Outcome & Evidence
- Generated improvement suggestions tied to the exact answer that triggered them, so feedback is actionable instead of generic.
- Tracked performance across sessions so a candidate can see which dimension is actually improving.
