How to Pass the Chubb Software Engineer Interview in 2026

The Chubb DNA (TL;DR)

Chubb's hiring process often features scenarios related to complex risk assessment, particularly for products like Polizza Multirischi Life Science. Interviewers look for candidates who can articulate how they manage ambiguity and regulatory frameworks, demonstrating a clear understanding of financial services and client needs.

The Chubb Interview Loop

Your onsite loop will typically consist of 5 rounds.

1
Round 1
Recruiter Screen
Motivation, role fit, logistics.
2
Round 2
Coding Screen
LeetCode-medium algorithmic problems under time pressure.
3
Round 3
System Design
Distributed systems, trade-offs at scale, architecture under constraints.
4
Round 4
Onsite Coding
LeetCode-hard, debugging, code clarity, edge cases.
5
Round 5
Behavioral / Leadership
Past evidence of ownership, influence, resolving conflict.

The Danger Zone: Top Reasons Candidates Fail

Based on our database of Chubb interview outcomes, avoid these common traps:

Claiming they never received difficult feedback.
Inefficiently comparing elements between the two lists (e.g., nested loops).
Choosing a single database technology without considering different data access patterns.
Using inefficient algorithms (e.g., checking all requests in a window).

Test Yourself: Real Chubb Questions

Three real prompts pulled from our database.

Type · Algorithmic

Implement a function to detect fraudulent transactions based on a set of rules (e.g., transaction amount exceeds a threshold, multiple transactions from the same IP in a short period). The function should return a list of transaction IDs flagged as potentially fraudulent.

Type · System Design

Design a system to process and analyze a high volume of incoming insurance claims data in near real-time. Consider data ingestion, validation, initial processing, and storage for subsequent analysis.

Type · Debugging

Here is a piece of code intended to calculate the total insured value across multiple policies. It's producing incorrect results for certain edge cases (e.g., policies with zero value, overlapping coverage periods). Debug and fix the code.

9 of 13 questions shown

Recruiter Screen

1
Type · Motivation
Why are you interested in a Software Engineer role specifically within the finance/insurance industry, and what aspects of Chubb's work in this domain appeal to you?

Coding Screen

2
Type · Algorithmic
Given a list of financial transactions, each with a timestamp, amount, and type (e.g., 'deposit', 'withdrawal', 'fee'), write a function to calculate the running balance. Handle potential edge cases like out-of-order transactions or invalid amounts.
3
Type · Algorithmic
Implement a function to detect fraudulent transactions based on a set of rules (e.g., transaction amount exceeds a threshold, multiple transactions from the same IP in a short period). The function should return a list of transaction IDs flagged as potentially fraudulent.

System Design

4
Type · System Design
Design a system to process and analyze a high volume of incoming insurance claims data in near real-time. Consider data ingestion, validation, initial processing, and storage for subsequent analysis.
5
Type · System Design
Design an API service that allows insurance agents to quickly retrieve policyholder information based on various criteria (policy number, name, address). The service needs to be highly available and performant, querying potentially large datasets.

Onsite Coding

6
Type · Coding
Write a function to simulate the process of calculating insurance premiums. This involves taking various inputs (coverage amount, risk factors, deductibles, location data) and applying a complex set of business rules. Ensure the code is modular and testable.
7
Type · Debugging
Here is a piece of code intended to calculate the total insured value across multiple policies. It's producing incorrect results for certain edge cases (e.g., policies with zero value, overlapping coverage periods). Debug and fix the code.

Behavioral / Leadership

8
Type · Behavioral
Tell me about a time you had to work with a stakeholder (e.g., product manager, business analyst) who had unclear or changing requirements. How did you approach the situation, and what was the outcome?
9
Type · Behavioral
Describe a challenging technical problem you encountered on a past project. What steps did you take to diagnose and resolve it? What did you learn from the experience?
