Wise interview, pair programming to product round.

Wise documents each engineering round on its jobs site. Candidates report them in this order, with the product round third, as Wise's own page says. Expect weeks between rounds; one accepted candidate put the whole process at about two months.

Wise's pair programming round is 60 minutes on HackerRank with an engineer, scored on technical competency, problem solving and communication. Wise's own page asks you to explain your thinking and treat the interviewer as a colleague. The task candidates report most is a circuit breaker, and the reports say the interviewer changes the requirements partway through. Here is what the reported versions ask and how to take each.

• Implement a circuit breaker: Three states. Closed: calls go through and failures are counted. Open: after a threshold of failures, calls fail fast without touching the service. Half-open: after a cool-down, one trial call decides whether to close or open again. Keep the thresholds configurable and the clock injectable, so the cool-down can be tested without waiting.
• A circuit breaker with WebClient: Wrap the reactive call rather than blocking it: count errors and timeouts as failures, return a failed result immediately when open, and let exactly one request through when half-open. Say which errors should not count, such as a 4xx that is the caller's fault.
• A circuit breaker with response caching: When the circuit is open, return the last good response if it is fresh enough, with a clear rule for how old is too old. Keep caching separate from the breaker so each can be tested alone, and say what happens when nothing is cached.
• When the requirements change mid-interview: Candidates report the task growing while they code. Stop, restate the new requirement, and say where it fits in your design before typing. A design with small, separate pieces makes this cheap, which is exactly what the round is watching for.
• Talking while you code: Communication is one of the three scored areas. Say what you are about to do, why, and what you are not handling yet. Ask one clarifying question at the start about failure thresholds and timeouts.

Wise says the backend is primarily Java, but you can usually use the language you know best. Practise a circuit breaker once from scratch in 40 minutes, with a test for each state change, before the interview.

Wise has four core values and says its interviews assess values fit. The product round's customer focus maps straight onto the third.

• This isn't just a job, we're a revolution: the mission of making money move cheaply and quickly
• We get it done: shipping and owning the result
• Customers > team > ego: the order Wise asks you to decide in
• No drama. Good karma: disagree well and move on

The technical questions candidates report are practical and close to what Wise runs in production. The product and values questions are about impact, customers and how you work with product people.

Ranges from Levels.fyi's Wise software engineer pages for Greater London, read on 30 September 2026; the London range across all levels runs from about £50K to £184K. Wise shares trade on Nasdaq and the London Stock Exchange, so equity is listed stock. Tallinn, Budapest, Singapore and the other hubs pay on local bands; ask the recruiter for the hub's range.

1. Write a circuit breaker from scratch once, in the language you will use, with a test per state change and an injectable clock. Then add response caching on top without rewriting it.
2. Prepare a design for money moving at volume: a payment system and a rolling 24-hour total, both with idempotent ingestion and a clear answer on currency conversion.
3. Read Wise's own page for each round before it; the scored areas are listed there.
4. Bring two projects to the product round with the customer problem, the metric that moved and your own part in it.
5. Prepare one story per value, especially Customers > team > ego: a time you put the customer ahead of your team's preference.
6. For front-end roles, practise without an AI assistant: Wise does not allow AI tools in that pair programming round.

This guide covers Wise's software engineering loop. Product, analytics, operations and compliance roles have their own processes; Wise may use a case study, a take-home or a test for them. For management and leadership roles the loop is similar but the bar shifts to people, delivery and strategy, so pair it with the leadership interview prep hub. The bar for your exact role comes from the role-by-role guides, and the prep that actually transfers is spoken, so run a mock interview before the real one.
