How to Pass the ManyPets Software Engineer Interview in 2026
The ManyPets DNA (TL;DR)
The ManyPets 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 ManyPets interview outcomes, avoid these common traps:
- Focusing only on the technical details without addressing the interpersonal dynamics.
- Ignoring scalability concerns for a growing user base.
- Focusing only on the outcome without detailing the learning journey.
- Not considering how to make the code more testable (e.g., dependency injection, smaller functions).

9 of 15 questions shown
Recruiter Screen
1- 1
Type · motivation
What interests you about working at ManyPets, specifically within the fintech and pet insurance space?
Coding Screen
3- 2
Type · algorithmic
Given a list of customer transactions (each with a timestamp, amount, and customer ID), write a function to calculate the total value of transactions for each customer within any given 24-hour rolling window. Optimize for performance. - 3
Type · algorithmic
Implement a system to detect potential fraudulent transactions. Given a stream of transactions, identify any transaction that is unusually large compared to the customer's historical average, or occurs immediately after a series of small, rapid transactions from the same customer. Define 'unusually large' and 'rapid' with reasonable heuristics. - + 1 more questions in this round (sign up to unlock)
System Design
3- 4
Type · design
Design a system to manage and process pet insurance claims. Consider the lifecycle from claim submission to payout, including data storage, validation, and integration with third-party services (e.g., vet databases, payment gateways). - 5
Type · design
Design a real-time notification system for policy renewals and claim status updates. How would you ensure notifications are delivered reliably and promptly to users across different channels (email, SMS, in-app)? - + 1 more questions in this round (sign up to unlock)
Onsite Coding
4- 6
Type · algorithmic
Implement a rate limiter for API requests to protect backend services. The rate limiter should support different limits per API key and per IP address, and should be efficient for high-throughput scenarios. - 7
Type · algorithmic
You are given a large dataset of customer interactions (e.g., website visits, policy changes, claim submissions) with timestamps. Design and implement a function to find the longest sequence of interactions for a single customer where each interaction occurs within 15 minutes of the previous one. - + 2 more questions in this round (sign up to unlock)
Behavioral / Leadership
4- 8
Type · collaboration
Tell me about a time you had a significant technical disagreement with a colleague or team lead. How did you approach the situation, and what was the outcome? - 9
Type · ownership
Describe a situation where you took ownership of a complex technical problem or project that wasn't strictly within your defined responsibilities. What motivated you, and what was the impact? - + 2 more questions in this round (sign up to unlock)

Sample answers
What a strong answer to these ManyPets interview questions shows.
How would you design a system to detect and prevent duplicate policy applications or duplicate claims? Consider potential edge cases and the need for performance.
A strong answer shows: Handling of concurrency and race conditions; Strategies for duplicate detection (e.g., hashing, fuzzy matching); Performance optimization.
Here is a Python function that's supposed to calculate the average claim amount per policy type, but it's producing incorrect results for certain inputs. Debug and fix the code. [Provide a buggy code snippet involving nested loops, potential division by zero, or incorrect aggregation].
A strong answer shows: Systematic debugging process; Identification of edge cases; Clean and correct code.
