The Aiven Interview Loop
Your onsite loop will typically consist of 5 rounds.
- 1
Round 1
Recruiter ScreenMotivation, role fit, logistics. - 2
Round 2
Coding ScreenLeetCode-medium algorithmic problems under time pressure. - 3
Round 3
System DesignDistributed systems, trade-offs at scale, architecture under constraints. - 4
Round 4
Onsite CodingLeetCode-hard, debugging, code clarity, edge cases. - 5
Round 5
Behavioral / LeadershipPast evidence of ownership, influence, resolving conflict.
The Danger Zone: Top Reasons Candidates Fail
Based on our database of Aiven interview outcomes, avoid these common traps:
- Lack of clear error handling and response codes.
- Ignoring security concerns like proper authentication and authorization.
- Focusing solely on personal career goals without connecting them to Aiven's needs.
- Not considering user-specific configurations or query patterns.

Recruiter Screen
1- 1
Type · Motivation
What interests you about working at Aiven, and how do you see your skills contributing to our mission of making data infrastructure accessible and manageable?
Coding Screen
3- 2
Type · Algorithmic
Given a list of Aiven service deployments with their start and end times, write a function to find the maximum number of services running concurrently at any point in time. Assume times are integers. - 3
Type · Data Structures
Implement a data structure that supports adding a new Aiven Kafka topic, retrieving all topics created within a given time range, and deleting a topic. Consider the trade-offs for each operation. - + 1 more questions in this round (sign up to unlock)
System Design
4- 4
Type · API Design
Design an API for Aiven's platform that allows users to programmatically manage their service instances (create, update, delete, list). Consider aspects like authentication, rate limiting, and idempotency. - 5
Type · Scalability
Aiven manages many distributed data services. How would you design a system to monitor the health and performance of thousands of Kafka and PostgreSQL instances globally, ensuring low latency alerts for critical issues? - + 2 more questions in this round (sign up to unlock)
Onsite Coding
3- 6
Type · Debugging
A user reports intermittent high latency when querying their Aiven for Elasticsearch cluster. You suspect an issue with indexing or shard allocation. How would you approach debugging this problem? - 7
Type · Code Clarity
Refactor the following code snippet, which processes Aiven billing data, to improve its readability, maintainability, and efficiency. Explain your changes. - + 1 more questions in this round (sign up to unlock)
Behavioral / Leadership
3- 8
Type · Conflict Resolution
We often debate whether to prioritize upstream open-source contributions versus implementing proprietary Aiven-specific features to meet customer demand. Tell me about a time you had to advocate for a specific technical path when the team was split between two competing architectural priorities. How did you align the team on the long-term impact on our service reliability? - 9
Type · Ownership
Aiven manages thousands of nodes across multiple cloud providers. Describe a time you identified a recurring performance bottleneck in a distributed system that was not currently on the team's roadmap. What evidence did you gather to justify the shift in focus, and how did you ensure the fix was robust enough for a multi-tenant environment? - + 1 more questions in this round (sign up to unlock)
