Okta Staff Engineer Interview Experience
Status: Selected ✅
YOE: 10+
Tech Stack: Java Full Stack
Recently interviewed with Okta for a Staff Engineer role. Sharing my interview experience in case it helps others preparing for senior/staff-level backend positions.
Round 1 - Coding
LeetCode: Insert Delete GetRandom O(1) - Duplicates Allowed
https://leetcode.com/problems/insert-delete-getrandom-o1-duplicates-allowed/
- Discussion around the optimal approach, data structures, and complexity analysis.
- Follow-up questions on handling duplicates efficiently and edge cases.
Round 2 - Coding
LeetCode: Find Median from Data Stream
https://leetcode.com/problems/find-median-from-data-stream/
- Expected optimal solution using heaps.
- Discussion on balancing logic, complexity, and alternative approaches.
Round 3 - System Design
Design a Notification Service
The discussion was heavily focused on handling notifications that are critical and require timely delivery.
Topics discussed:
- Reliability and fault tolerance
- Retry mechanisms
- Prioritization of messages
- Delivery guarantees
- Scalability considerations
- Handling failures and backpressure
- Trade-offs in design decisions
Round 4 - Hiring Manager Round
Mainly focused on:
- Current project and technical ownership
- Prioritization of work and decision-making
- Stakeholder management
- Collaboration and leadership
- Behavioral questions
Overall
The process was a good mix of coding, system design, and leadership evaluation. For both the coding rounds interviewer asked for hard kind problems. For Staff Engineer roles, interviewers seem to focus not only on problem-solving ability but also on design thinking, ownership, prioritization, and the ability to make engineering trade-offs. For design round focus on things like kafka partition key, ordering, critical messages vs non-critical, sqs vs kafka here(I chose sqs at end).
Hope this helps future candidates. Feel free to reach out if you have any questions.
