Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
About your past
Tell me about a custom login experience you built with Okta APIs or the sign-in widget.
What they are checking: Whether they have hands-on Okta development experience with APIs or the sign-in widget, not only console configuration.
Tell me about a time you explained an identity issue to an application team that didn't understand federation.
What they are checking: Whether they can explain identity concepts to application teams simply and patiently, since many integration problems come from misunderstanding.
What would you do
Users in one region suddenly can't sign in to a cloud app through Okta. How do you troubleshoot?
What they are checking: Whether they troubleshoot sign-in failures methodically through logs and configuration, isolating the failing component instead of guessing under pressure.
What's your approach to rolling out FIDO2 or phishing-resistant MFA to a workforce of 80,000?
What they are checking: Planning a large MFA change with support and fallback paths.
About the work
Walk me through a SAML 2.0 login from the moment a user clicks the app to when they land inside it.
What they are checking: Real understanding of the federation flow and where it can break.
When would you choose OIDC over SAML for a new application integration?
What they are checking: Whether they know when OIDC fits better than SAML, such as for modern web and mobile apps, and can explain the trade-offs.
How would you design federation between Entra ID, Okta and Ping Federate without creating confusing login paths?
What they are checking: Whether they can design clear federation across several identity providers, so users get one predictable login path instead of confusing choices.
How does OAuth 2.0 differ from authentication, and why does that matter when teams integrate APIs?
What they are checking: Whether they clearly separate authorization from authentication, since confusing the two leads teams to build insecure API integrations.
A user is provisioned in the HR system but never shows up in a downstream app. Where do you look?
What they are checking: Whether they understand provisioning chains like HR feeds, directory sync and SCIM, and can trace exactly where a user record stopped.
How do you handle a certificate expiring on a federation trust without causing an outage?
What they are checking: Whether they track and rotate federation certificates ahead of expiry with partners, because a missed rotation can lock out every user of an app.
How do customer identities change your design compared with workforce identities?
What they are checking: Whether they understand how customer identity differs, with larger scale, self-service registration and privacy rules, compared with employee sign-in.
