Multi-Platform Interview Software -- 2

I want a single, easy-to-use application that lets me sit at one desk and interview candidates across all of my social channels—Facebook, Twitter, LinkedIn, and WhatsApp—without jumping between separate apps or browser tabs.

The core workflow is simple: I choose a candidate profile, schedule a slot, launch an audio or video call directly from the dashboard, and the software automatically records the entire session while preserving the full chat transcript. After the interview ends, I should be able to replay the recording, download it, or share a secure link with my team.

Because these interviews may be booked back-to-back, the scheduler must prevent conflicts and send automatic reminders. Seamless chat integration is also essential so that any pre-interview messages exchanged on the candidate’s original platform appear in the same unified thread inside the app.

Deliverables you will hand over to me:
• Cross-platform desktop or web application that connects to Facebook, Twitter, LinkedIn, and WhatsApp APIs
• Built-in calendar and reminder system for booking and rescheduling interviews
• One-click audio/video calling with automatic call recording and cloud/local storage options
• Real-time chat pane that mirrors messages from each native platform
• Admin panel to manage multiple social media accounts, recordings, and user permissions
• Clean source code, installation package, and brief user documentation in English or Hindi

Please use mainstream, well-supported technologies (for example, Node.js, React, Electron, WebRTC, Twilio or equivalent) so future maintenance is straightforward. Include API keys or setup instructions I can replicate on my own accounts. Acceptance will be based on successful log-in to all four platforms, a test interview that records correctly, and smooth export of the resulting audio/video file and chat log.
