AI Voice Technical Interviews& Code Candidates Must Defend.
Take first-round screens off your interviewers' calendars. Candidates build in a sandboxed editor, then defend their code to an AI voice interviewer, and your reviewers get an evidence pack with integrity signals to make the call. Built for Universities, Bootcamps & Hiring Teams.
Native LMS Integrations & Isolated Execution Infrastructure
"In your distributed key-value store, what happens when a network partition isolates your Raft leader from quorum?"
"Heartbeats fail, term counter increments, and the isolated leader cannot achieve quorum. A new leader is elected in the majority partition, and uncommitted writes on the old leader are safely rolled back."
"Correct. Now how would you handle linearizable reads on the followers without incurring consensus log disk I/O?"
LMS Integrations & Technical Execution Stack
Standards-based LTI 1.3 interoperability with campus learning management systems and isolated container sandboxes.
/ audience & solutions
Built for three distinct audiences.
Find the exact problem Edulexa solves for your organization.
Screen whole cohorts asynchronously. Make pasted ChatGPT answers hard to pass off.
Campus placement cells cannot afford to manually interview hundreds of candidates. Edulexa automates the first technical round with voice defense and integrity-monitored coding sandboxes, and your staff review the evidence.
- ✓ Automated batch candidate rankings & leaderboards
- ✓ Keystroke/paste replay & tab-switch logging
- ✓ 1-Click LTI 1.3 Canvas / Blackboard integration
- ✓ Shareable scorecards for recruiting drives
AI voice mock interviews + 90-second voice cart recovery.
Stop paying human senior engineers $150/hr for student mock interviews. Give students AI voice practice and follow up on abandoned checkouts automatically.
- ✓ 90s outbound voice call to abandoned cart leads
- ✓ Staff Architect & Security interview personas
- ✓ Per-viewer video watermarking & signed URLs
- ✓ 1099-NEC records & ACH batch payouts (beta)
Practice high-stakes FAANG interviews with an AI that talks back.
Puzzle drills rarely test it, but real interviews ask you to defend your architecture and trade-offs out loud. Practice with an AI that challenges your design choices in real time.
- ✓ Realistic voice conversations over your microphone
- ✓ Real-world sprint sandboxes (Rust, TS, Python, C#)
- ✓ Verifiable LinkedIn skill credentials & passports
- ✓ 1-on-1 office hours booking with vetted mentors
/ how it works
From setup to verifiable results in 3 steps.
No complex installations. Humans review evidence instead of running every screen.
Send Link or Launch from LMS
Universities, bootcamps, and recruiters send an assessment link or embed it inside Canvas, Blackboard, or Moodle with 1-click LTI 1.3 integration.
Candidate Speaks & Codes
The candidate puts on their headset. The AI voice agent questions them out loud about their architecture and code decisions, while keystroke replay, tab logging, and similarity checks gather integrity signals.
Evidence Pack & Verified Badge
Reviewers get a 6-pillar radar score, full code playback, and integrity signals, and make the decision. Candidates earn a verifiable credential badge to display on LinkedIn.

Why Institutions Choose Edulexa.
Static coding questions are easy to answer with a second screen or ChatGPT. Edulexa pairs live voice defense of the candidate's own code with an integrity-monitored sandbox.
| Evaluation Capability | Edulexa PlatformRECOMMENDED | Legacy Coding Tests (HackerRank, LeetCode) | Human Interviewers (Karat, Internal Eng) |
|---|---|---|---|
| Real-Time AI Voice Defense | ✓Real-time conversational AI (Staff Architect personas question the candidate's own code and trade-offs) | ❌ Text-only (No voice conversation or trade-off defense) | Human engineers ($150+/hr, high fatigue) |
| AI-Assisted Cheating Signals | ✓Keystroke/paste replay, cross-candidate similarity, tab logging, and verbal defense, for human review | ❌ A pasted answer looks the same as an earned one | Manual observation (pristine but subjective) |
| Campus Scale | ✓Asynchronous: whole cohorts sit the assessment without interviewer scheduling | Static code submission only (no verbal verification) | ❌ Takes weeks to schedule across 500 students |
| Candidate Scorecard | ✓6-pillar radar score + evidence pack + verifiable SHA-256 integrity hash | Pass/fail unit test score without composure/depth analysis | 2 to 4 days delay for human interview notes |
| Social Credential / Badge | ✓1-Click LinkedIn Skill Passport with a public verification page | ❌ None or basic PDF certificate | ❌ Private internal recruiter notes only |
| 90s Voice Cart Recovery | ✓AI outbound voice agent calls dropped checkouts within ~90s | ❌ No revenue recovery tooling | ❌ Manual admissions phone calls (24-48 hrs late) |
| Cost Per Evaluation | ✓Included in plan pricing (see /pricing) | Typically per-seat subscriptions | Interviewer time per candidate |
