A practice interview app that uses LiveDataTechnologies–style workforce data (People Data Dictionary) to match your job history to similar professionals and suggest a role to practice for. You get a behavioral mock interview with webcam and microphone, plus scored metrics and visualizations.

• Job history input – Enter company, years, salary, role type (intern, full-time, part-time, etc.), and title. Data shape aligns with LiveDataTechnologies job level, function, and company fields.
• Similarity matching – Your history is compared to a mock workforce database (schema: level, function, location_details, started_at_details). We find people with similar roles/companies and use their current jobs as suggested next roles.
• Mock interview – 5 behavioral questions for the suggested job, 2 minutes per answer. Uses your webcam and microphone.
• Scoring – Tone and speaking time are derived from live audio; eye contact and response quality use the same pipeline (CV-based eye contact can be wired to MediaPipe/Face Mesh later).
• Results – Overall score, radar chart of metrics, per-question bar charts, and time-per-question view.

• Jobs: title, level, function, company (name, industry, etc.), location, location_details, started_at, started_at_details (confidence).
• People: job_history + current_position (where they work now).

Mock data in lib/mock-livedata.ts follows this schema; you can swap in the real LiveDataTechnologies People API when you have credentials.
