How to Pass the Yoco Software Engineer Interview in 2026
The Yoco DNA (TL;DR)
The Yoco 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 Yoco interview outcomes, avoid these common traps:
- Not being able to articulate the impact or outcome of their initiative.
- Incorrect handling of date range filtering or aggregation logic.
- Failing to articulate their own reasoning clearly.
- Using a naive approach like concatenating and then sorting, which ignores the pre-sorted nature of the input.

What interests you about Yoco's mission to help small businesses grow, and how does that align with your career aspirations as a Software Engineer?
Coding Screen
3- 2
Type · algorithmic
Given a list of customer transactions for a small business, write a function to calculate the total amount processed by Yoco for each unique merchant ID within a given date range. Assume transactions are represented as dictionaries with keys 'merchant_id', 'amount', and 'timestamp'. - 3
Type · algorithmic
Implement a function that takes a list of Yoco payment statuses (e.g., 'pending', 'successful', 'failed', 'refunded') and returns the percentage of successful payments. Handle potential division by zero if there are no payments. - + 1 more questions in this round (sign up to unlock)
System Design

Type · design
Design a system to detect fraudulent Yoco transactions in real-time. Consider the data sources, processing pipeline, detection mechanisms, and alerting. - 5
Type · design
Design a system to manage and display Yoco's merchant dashboard, showing key metrics like sales volume, transaction counts, and chargeback rates. How would you handle data aggregation and caching for performance? - + 1 more questions in this round (sign up to unlock)

Type · debugging
Here is a Python function intended to calculate the average transaction value for a given merchant. It has several bugs. Please find and fix them, and explain your thought process. - 7
Type · algorithmic
Implement a function to determine if a given Yoco transaction ID is valid according to a specific format (e.g., starts with 'txn_', followed by 8 alphanumeric characters). Consider performance for a large number of checks. - + 1 more questions in this round (sign up to unlock)

Sample answers
What a strong answer to these Yoco interview questions shows.
Tell me about a time you received constructive criticism that was difficult to hear. How did you process it, and what actions did you take as a result?
A strong answer shows: Self-awareness; Coachability; Growth mindset; Resilience.
Given a stream of Yoco transaction amounts, design an algorithm to efficiently find the median transaction amount at any point in time. Discuss the trade-offs of your approach.
A strong answer shows: Use of appropriate data structures (e.g., two heaps).; Correct logic for maintaining the median.; Discussion of time and space complexity.; Ability to handle a continuous stream of data..
