How DD Assessments Works Under the Hood
A complete technical and operational breakdown of our multi-tenant recruitment assessment platform—from instant token generation to server-side auto-grading and executive candidate analytics.
Secure Tokenization & Dispatched Candidate Invites
Eliminate open, unvetted test links. Every candidate assessment journey begins with a cryptographically secure, single-use invitation token generated directly from the HR dashboard.
- Custom Token Generation: System constructs a 32-character high-entropy cryptographic token tied specifically to a designated candidate reference ID and selected job role.
- Time-Bound Security Windows: HR sets customizable expiration parameters (e.g., 7 or 14 days). Once expired or submitted, the token automatically invalidates to prevent unauthorized re-attempts.
- Multi-Channel Dispatch: Invite URLs can be distributed via SMS, WhatsApp API, or direct ATS email integration—allowing high-volume candidates to access the portal directly from mobile devices.

Candidate Introduction, Rules & Practice Verification
Anxiety-reducing onboarding designed for accessibility across all digital literacy levels. Candidates are guided through clear test rules and practice questions before any timers start.

- Two Practice Sample Questions: Candidates complete interactive sample items (Numeracy and Safety) to understand answer selection without burning official test time.
- Transparent Testing Terms: Clear instructions outline the strict 45-minute maximum limit, the 50-question structure, and the requirement for continuous focus.
Practice Sample Q1 (Numeracy)
Stock log records 50 items. 15 items are dispatched. What is the balance?
