Engineering

Indian job portals are two-sided marketplaces where the OTP layer has to satisfy candidates (low friction sign-up), recruiters (high accountability for contact unlocks), and platform-side fraud teams (defending the reputation of both).

Why Job Portals Use OTP

  • Candidate phone verification at sign-up.
  • Recruiter login + sensitive-action step-up.
  • Application-confirmation SMS to candidate.
  • Recruiter contact-unlock for premium tiers.

OTP Flows on Both Sides

Candidate side:

  1. Sign-up OTP.
  2. Application-submit confirmation SMS.
  3. Interview-reminder SMS.
  4. Account-recovery OTP.

Recruiter side:

  1. Sign-up OTP.
  2. Contact-unlock OTP per candidate.
  3. Bulk-action step-up OTP.

Recruiter Contact-Unlock

Pattern: when a recruiter requests a candidate’s contact, system emits OTP to recruiter’s phone. Recruiter enters; system delivers contact and logs the transaction. This both audit-trails the unlock and defeats casual session-hijacking.

Resume / Recruitment Fraud Defences

  • Phone-verified resumes win trust signals on listings.
  • Disposable-number sign-ups flagged via virtual-number lists.
  • Recruiter accounts with abnormal unlock-rate auto-paused.

FAQ

StartMessaging handles candidate and recruiter OTP traffic on a single API key — bulk-unlock workflows get the same idempotency guarantees as one-at-a-time.
