How to Pass the Anyfin Software Engineer Interview in 2026

The Anyfin DNA (TL;DR)

Anyfin's 'Anyfin Refinansiering' product success hinges on candidates demonstrating clear, actionable judgment in complex financial scenarios, often probed through hypothetical product improvements or market shifts. The interview loop assesses a candidate's capacity to drive tangible impact for users.

The Anyfin 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 Anyfin interview outcomes, avoid these common traps:

Focusing only on the application layer and neglecting database or third-party API limitations.
Incorrectly handling date comparisons or filtering by month.
Incorrectly deriving or implementing the components of expected loss (e.g., PD, LGD, EAD).
Producing an unsorted output array.

Test Yourself: Real Anyfin Questions

Three real prompts pulled from our database.

Type · behavioral

We often deal with legacy data pipelines that grow complex as we expand into new European markets. Tell me about a time you identified a bottleneck in an existing, stable service that was not currently failing but would have prevented us from scaling to a new market. What was your process for identifying this hidden risk and ensuring it was addressed?

Type · algorithmic

Given a dataset of historical loan performance (e.g., loan ID, principal, interest rate, default status, repayment dates), write a function to calculate the expected loss for a portfolio of new loans. Assume a simplified model where expected loss is `Probability of Default * Loss Given Default * Exposure at Default`.

Type · debugging

Here is a snippet of code that is supposed to calculate the average interest rate of approved loans. It's producing incorrect results for certain inputs. Debug and fix the code. [Provide a buggy code snippet, e.g., incorrect loop bounds, type casting issues, floating point precision errors, or flawed conditional logic].

9 of 13 questions shown

Recruiter Screen

1
Type · motivation
What specifically about Anyfin's mission to help consumers manage their debt and improve their financial lives resonates with you?

Coding Screen

2
Type · algorithmic
Given a list of loan applications, each with an amount, interest rate, and application date, write a function to calculate the total interest accrued for all approved loans within a given month, considering that loans are approved if their interest rate is below a certain threshold and they were applied for within that month. Assume a simple interest calculation.
3
Type · algorithmic
Imagine a system that tracks customer transaction volumes for different financial products (e.g., loans, savings accounts). Given a stream of transactions, each with a product ID and amount, design a data structure and algorithm to efficiently retrieve the total transaction volume for any given product ID in O(1) time after an initial O(N) build time, where N is the number of transactions.

System Design

4
Type · system-design
Design a system to detect fraudulent loan applications in real-time. Consider the data sources, processing pipeline, detection mechanisms, and how to handle false positives/negatives.
5
Type · system-design
Design a notification service for Anyfin customers. This service should be able to send various types of notifications (e.g., payment reminders, loan approval status, new product offers) via multiple channels (SMS, email, push notifications). Consider reliability, scalability, and user preferences.

Onsite Coding

6
Type · algorithmic
Implement a function that takes a list of financial transactions (each with a timestamp, amount, and type - e.g., 'deposit', 'withdrawal') and returns the running balance after each transaction. Handle potential out-of-order transactions by sorting them first. Ensure the implementation is efficient and handles large datasets.
7
Type · debugging
Here is a snippet of code that is supposed to calculate the average interest rate of approved loans. It's producing incorrect results for certain inputs. Debug and fix the code. [Provide a buggy code snippet, e.g., incorrect loop bounds, type casting issues, floating point precision errors, or flawed conditional logic].

Behavioral / Leadership

8
Type · behavioral
Tell me about a time you had to make a significant technical decision with incomplete information or under tight deadlines. How did you approach it, what was the outcome, and what did you learn?
9
Type · behavioral
At Anyfin, we balance rapid product iteration with the high reliability required for financial services. Describe a specific instance where you advocated for slowing down a feature release to address technical debt or stability concerns, despite pressure to meet a growth-related deadline. How did you balance the business need for speed against the long-term cost of that debt?
