How to Pass the ManyPets Software Engineer Interview in 2026
The ManyPets DNA (TL;DR)
The ManyPets interview structure aims to identify individuals who can elevate the Pet Insurance offering, showcasing innovative thinking and a deep commitment to financial product excellence. They specifically look for contributions that uphold their 'Provider Of The Year' reputation.
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).

Test Yourself: Real ManyPets Questions
Three real prompts pulled from our database.
Type · debugging
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].
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.

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)
