// anti-cheat.built-in
Every TrialDay session is monitored for engagement integrity. We surface what matters to recruiters — without the surveillance baggage of full-screen lockdown tools.
Focus score (0–100)
Tab-switches, large pastes, and copy-outs are tracked per session. Each candidate row shows a color-coded focus chip next to their score.
AI-graded responses
Every typed answer is rated for technical precision in real time — flagged as strong, vague, or off-topic with the exact quote shown in the report.
Adaptive difficulty
Scores adjust for difficulty. A 70 on Challenging beats an 85 on Introductory — apples-to-apples across your entire candidate pool.

Paste a job description. Get a shareable simulation link in 60 seconds. Every candidate who completes it gets an automated behavioral report — before your first interview.
Behavioral signals, not vibes
Did they escalate the right ticket first? Did they ignore a P1 to work on something easier? Did they communicate proactively or wait to be asked? Every choice is logged and scored.
Tool time heatmap
30 min in Slack, 5 min in Jira, 45 min in Terminal — see where candidates actually spent their time. Priority inversion and idle gaps surface automatically, before you read a résumé.
Custom scenarios from your JD
Paste a job description and get a simulation in 60 seconds. Paste your own Jira tickets and Slack threads for even more realism — candidates work your actual environment, not a generic case study.
// what-people-say
Real feedback from people who've simulated before their interviews — and the managers who screened with TrialDay.
Did the SRE simulation the night before my loop at a major cloud company. The Slack pressure and incident triage felt uncomfortably real. Ended up getting the offer.

I've run 3 different roles now — SWE, PM, and growth. Every time the teammates feel distinct and the challenge catches me off guard. Nothing else gets this close to actual work.
Mei-Lin C.
PM transitioning from consulting
We screened 14 candidates with a custom SWE simulation before the first phone call. The behavioral signals — who escalated, who stayed silent, who identified root cause — were more predictive than any take-home we've used.
