The Steeple DNA (TL;DR)
The Steeple 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 Steeple interview outcomes, avoid these common traps:
- Focusing solely on compensation or benefits rather than the role and company.
- Not considering all layers of the system (frontend, API, database, caching).
- Using a monolithic relational schema for all content types without considering specialized needs.
- Failing to communicate the impact of the unplanned work to the team lead

What interests you about Steeple's mission to improve workplace collaboration and productivity through our SaaS platform?
Coding Screen
3- 2
Type · Data Structures & Algorithms
Given a list of user activity events (timestamp, user_id, action_type), write a function to find the most active user within a given time window. Assume events are not necessarily sorted by timestamp. - 3
Type · String Manipulation
Implement a function to parse and validate Slack-like notification strings (e.g., '@user mentioned you in #channel'). Extract the user and channel information. - + 1 more questions in this round (sign up to unlock)
System Design
3- 4
Type · Scalability
How would you design a real-time notification system for Steeple that can handle millions of concurrent users receiving updates about their tasks and mentions? - 5
Type · Database Design
Steeple's user base is growing rapidly. How would you design the database schema to efficiently store and query user-generated content like comments, task updates, and mentions, considering potential performance bottlenecks? - + 1 more questions in this round (sign up to unlock)
Onsite Coding
3- 6
Type · Algorithmic Problem
Given a stream of task completion events, implement a data structure that can efficiently calculate the average completion time for tasks created in the last N minutes. Assume tasks have creation and completion timestamps. - 7
Type · Debugging
A user reports that their dashboard is occasionally showing incorrect data counts. Describe your process for debugging this issue, assuming the data is fetched from a backend API. - + 1 more questions in this round (sign up to unlock)
Behavioral / Leadership
3- 8
Type · Collaboration
At Steeple, we often balance building new features for our SaaS dashboard against technical debt in our notification delivery service. Tell me about a time you had to advocate for a specific path during a product roadmap planning session where your engineering team and the product team had conflicting priorities. How did you balance the need for speed with the long-term stability of the platform? - 9
Type · Ownership
We recently identified a latency spike in our real-time task sync API that was impacting user productivity metrics. Describe a time you identified a performance bottleneck in a production system that was not part of your current sprint goals. How did you validate the issue, prioritize its fix, and ensure it did not regress in future releases? - + 1 more questions in this round (sign up to unlock)
