How to Pass the Wise Software Engineer Interview in 2026
The Wise DNA (TL;DR)
English original + your local-language translation
Tech and global multinational interviews are most often conducted in English. For industries like luxury, finance, or pharma, the working language may be local. We show every question in English first — alongside your local-language translation — so you can prep in whichever language your interviewer ends up using.
The Wise 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 Wise interview outcomes, avoid these common traps:
- Using a single, monolithic notification service that becomes a bottleneck.
- Focusing only on personal career growth without mentioning Wise's mission or products.
- Giving a generic answer about wanting to work at a 'fast-paced tech company'.
- Failing to handle different currencies or making incorrect assumptions about conversion rates.

9 of 17 questions shown
Recruiter Screen
1- 1
Type · motivation
Why are you interested in working at Wise, specifically in a software engineering role within the fintech industry?
Coding Screen
3- 2
Type · data-structures
Given a list of recent international money transfers, each with a sender, receiver, amount, currency, and timestamp, write a function to calculate the total amount sent from country X to country Y in the last 24 hours, considering currency conversions. - 3
Type · algorithms
Implement a function that detects potential duplicate transactions based on sender, receiver, amount, and a small time window (e.g., 5 minutes). Assume transactions are coming in a stream. - + 1 more questions in this round (sign up to unlock)
System Design
3- 4
Type · distributed-systems
Design a system to process and reconcile international payments across multiple banking partners and currencies. How would you ensure consistency and handle failures? - 5
Type · scalability
Wise handles millions of transactions daily. How would you design a notification system to alert users about their transaction status (e.g., sent, received, delayed) at scale? Consider real-time updates and potential bottlenecks. - + 1 more questions in this round (sign up to unlock)
Onsite Coding
3- 6
Type · algorithms
You are given a large, sorted list of currency exchange rates that change over time. Write an efficient algorithm to find the best possible exchange rate path between two currencies, potentially involving intermediate currencies, to minimize the cost for a transfer. - 7
Type · debugging
A user reports that their transfer is stuck in a 'pending' state for much longer than usual. You have access to logs showing the transaction's journey through various microservices (e.g., validation, FX, compliance, settlement). Debug this issue by analyzing the provided (hypothetical) logs and identifying the root cause. - + 1 more questions in this round (sign up to unlock)
Behavioral / Leadership
7- 8
Type · Past Experience
Tell me about a time you had to influence a team or stakeholder without having direct authority. What was the situation, what did you do, and what was the outcome? - 9
Type · Problem Solving
Describe a situation where you faced a significant technical challenge or roadblock in a project. How did you overcome it? - + 5 more questions in this round (sign up to unlock)
