- 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 HockeyStack interview outcomes, avoid these common traps:
- Inefficiently iterating through user activity logs.

Recruiter Screen
1- 1
Type · Motivation
What interests you about HockeyStack specifically, and how do you see your skills contributing to a SaaS company focused on product analytics?
Coding Screen
3- 2
Type · Algorithm
Given a stream of user events (e.g., page views, button clicks) with timestamps and user IDs, design an algorithm to calculate the daily active users (DAU) and monthly active users (MAU) efficiently. Assume events can arrive out of order. - 3
Type · Algorithm
Implement a function that takes a list of user sessions, where each session is a list of timestamps, and returns the average session duration. Ensure you handle sessions with zero or one event correctly. - + 1 more questions in this round (sign up to unlock)
System Design
3- 4
Type · System Design
Design a system to track user feature adoption for a SaaS product. Users can enable/disable features. The system should report which users have adopted which features over time, and the rate of adoption for new features. - 5
Type · System Design
Design a real-time notification system for HockeyStack. When a significant event occurs (e.g., a user's trial is ending, a key metric drops), users should receive an in-app or email notification. Consider delivery guarantees and scalability. - + 1 more questions in this round (sign up to unlock)
Onsite Coding
4- 6
Type · Algorithm
Implement a function to calculate the 'stickiness' of users based on their activity frequency within a given period (e.g., N-day stickiness). Define 'activity' and 'frequency' clearly. Consider edge cases like users with very sparse or very dense activity. - 7
Type · Debugging
A user reports that their analytics dashboard is showing incorrect data for conversion rates. Here's a simplified snippet of the code responsible for calculating conversion rates. Debug and fix it. - + 2 more questions in this round (sign up to unlock)
Behavioral / Leadership
6- 8
Type · Conflict Resolution
Tell me about a time you had a significant disagreement with a colleague or manager. How did you approach the situation, and what was the resolution? - 9
Type · Adaptability
Tell me about a time when a product or strategy you were working with changed significantly with little notice. How did you adapt, and what did you learn from the experience? - + 4 more questions in this round (sign up to unlock)
