Okta Software Engineer Interview Questions

1.Tell me about a time when you discovered a security vulnerability or potential risk in code you were working on. How did you handle it?

2.Describe a time when you went above and beyond to solve a customer problem, even when it wasn't directly your responsibility.

3.Tell me about a time when you had to collaborate with multiple teams to deliver a complex feature or project. What challenges did you face and how did you overcome them?

4.Describe a situation where you had to balance shipping a feature quickly with ensuring high code quality. How did you make that tradeoff decision?

5.Tell me about a time when you had to make a difficult decision that affected your team, where transparency and doing the right thing conflicted with easier alternatives.

6.Describe a time when you identified an opportunity to innovate or improve an existing system, but faced resistance from stakeholders. How did you drive change?

7.Write a function that validates whether a given JWT token is valid and not expired. Assume you have access to the signing key.

8.Write a function that takes a username and password and returns whether the credentials are valid. Consider what security measures you'd implement.

9.You need to implement a user permission system where users can have multiple roles, and roles can have overlapping permissions. How would you design the database schema and query for checking if a user has a specific permission?

10.Debug this code: users are complaining that Single Sign-On occasionally fails with a 'token expired' error, but the tokens should be valid for 24 hours. What could be causing this?

11.You're designing an authentication service that needs to handle 10 million login requests per hour. Walk me through your approach to ensure both performance and security.

12.Implement a rate limiter that can handle 1000 requests per minute per user. The system should be distributed across multiple servers.

13.Design a session management system for Okta's SSO platform that maintains user sessions across 1,000+ integrated applications. How would you handle session lifecycle and security?

14.You need to design a notification system for Okta's Adaptive MFA that can send push notifications, SMS, and emails based on risk assessment. How would you architect this for global scale?

15.Design a real-time audit logging system for Okta that captures all authentication events, API calls, and admin actions across the platform. How would you ensure data integrity and compliance?

16.Build an OAuth token management system for Okta's API Access Management that handles token lifecycle, revocation, and refresh for millions of client applications. How do you ensure both security and performance?

17.Design Okta's Integration Network provisioning system that automatically creates and manages user accounts across 7,000+ third-party applications. How do you handle failures, retries, and data consistency?

18.Design a user deprovisioning system for Okta that immediately revokes access across all connected applications when an employee is terminated. How do you ensure zero security gaps while handling system dependencies?

19.Tell me about a time when you had to mentor or guide a less experienced team member. How did you approach helping them grow?

20.Describe a situation where you had to convince your team or stakeholders to prioritize paying down technical debt over building new features.

21.Tell me about a time when you had to learn a new technology or domain quickly to contribute to a project. How did you approach the learning process?

22.Describe a time when you identified that your team was working on something that wouldn't deliver the expected customer value. How did you handle the situation?

23.Tell me about a time when you had to coordinate a technical solution across multiple services or teams, where no single team owned the full solution. How did you drive alignment?

24.Describe a situation where you discovered something in production that could potentially impact security or customer data, but fixing it would require significant coordination. How did you handle it?

25.Okta's platform processes billions of authentication events monthly, but you notice login success rates dropped 2% last week. Walk me through how you'd investigate and quantify the business impact of this issue.

26.Estimate how many API calls Okta's Integration Network handles per day across all 7,000+ connected applications. Walk me through your reasoning and key assumptions.

27.A large enterprise customer reports that their employees can't access critical applications through Okta SSO, but only during their peak business hours. How would you diagnose this issue and what are the most likely root causes?

28.You're tasked with estimating the storage requirements for Okta's audit logs if we need to retain detailed authentication events for compliance. Walk through your analysis considering our customer scale and regulatory requirements.

29.Okta needs to decide whether to build a new identity verification feature in-house or acquire a specialized company. Given our platform's scale and security requirements, how would you structure this analysis and what factors would be most critical?

30.An enterprise customer wants to migrate 50,000 employees from their legacy identity system to Okta, but they can't afford any authentication downtime during business hours. Design your migration strategy and risk mitigation approach.
