Remitly·Software Engineer·Onsite - System Design / Architecture

May 2026
System design round at Remitly for a software engineering role. The whole session was basically one big elevator question that kept branching into scheduling algorithms, concurrency, and multi-elevator scaling. Dense but kind of interesting if you're into that stuff.
  • Design an object-oriented elevator system. Walk through the core classes and interfaces you'd define (elevator, controller, request, floor, buttons, sensors), how they interact, and how you'd handle concurrency and faults.
  • Given pending requests for floors [1, 99, 2], how does your scheduler guarantee stopping at floor 2 before floor 99, using only a single internal queue? Describe the queue operations, tie-breaking rules, and the time and space complexity.
  • Propose a scheduling algorithm for the elevator system that optimizes for both travel time and fairness across requests.
  • How does your design scale to multiple elevators, and how would you support peak traffic modes?

“I started with the obvious classes and felt okay until they pushed on concurrency.”

Remitly·Software Engineer·Onsite - Behavioral / Leadership

May 2026
Behavioral question from Remitly, looks like it was for a mid-to-senior level role. Just the one question shared, but it's a meaty one about pivoting mid-project.
  • Tell me about a project where the original approach wasn't working. What made you realize it, what other options did you consider, and how did it turn out?

“This one sounds straightforward but I think a lot of people trip up by spending too long on what the original plan was instead of getting to the pivot.”

Remitly·Product Manager·Hiring Manager Screen

May 2026
Remitly PM interview, one big behavioral question about keeping projects on track. Pretty much the whole conversation was built around one detailed scenario.
  • Walk me through how you keep a project on schedule. Cover how you scoped the work, identified and tracked risks, kept stakeholders in the loop, and adapted when things went sideways.

“This is a meaty question and I underestimated how much they wanted the full arc, not just the happy path.”

Remitly·Product Manager·Hiring Manager Screen

Jun 2026
One question from what seemed like a PM screen at Remitly. Not much to go on but it's a classic product sense angle that trips people up if they haven't thought about it before.
  • How do you gather feedback from users?

“Pretty open-ended and I kind of rambled.”

Remitly·Software Engineer·Onsite - System Design / Architecture

Jun 2026
System design round at Remitly for a software engineer role. The whole thing was basically one big URL shortener question but they expected you to go several layers deep across a lot of dimensions, not just sketch a box diagram and call it done.
  • Design a production-ready URL shortening service, covering the public API, database schema, ID generation with collision avoidance, caching strategy, partitioning and replication, rate limiting, analytics, TTL cleanup, high availability, and trade-offs under different traffic patterns.

“This question sounds scoped but it really isn't.”

Remitly·Software Engineer·Technical Phone Screen

Jun 2026
Remitly threw a classic debt-settlement problem at me, basically the same idea as LC 465. It was a coding round and the problem itself is well-known but getting to a minimum-transfer solution under pressure is a different thing.
  • Given a set of transactions or a map of accounts to net balances, write a function that produces the minimum number of transfers needed to settle all debts.

“I knew this problem from practice so I wasn't totally lost, but minimum transfers is where I slowed down.”

Remitly·Software Engineer·Technical Phone Screen

Jun 2026
Interviewed for a software engineering role at Remitly and got a coding problem that felt deceptively simple at first glance. The core challenge was about settling debts between accounts, which is the kind of thing you'd expect from a fintech company.
  • Given a map of account IDs to net balances (positive means owed money, negative means owes money, and the sum is guaranteed to be zero), produce a minimal list of transfers that settles all accounts to zero. Each transfer is a tuple of (sender, receiver, amount).

“My first instinct was to just pair up positives and negatives greedily, which actually works fine for correctness.”

Remitly·Software Engineer·Onsite - Multi Round

Jun 2026
Remitly's onsite for a software engineer role has four rounds: two coding, one system design, and a 'PM partnership' round that I wasn't totally sure how to prep for going in.
  • How does a 'PM partnership' interview differ from a standard behavioral interview, and what should you expect from it?
  • What specific competencies are evaluated when it comes to collaborating with product managers and other cross-functional partners?
  • How should you structure and prepare answers for a PM partnership round as a software engineer?

“I kept treating this like a regular behavioral round and I think that was a mistake.”

Remitly·Software Engineer·Onsite - Behavioral / Leadership

Jun 2026
Behavioral round at Remitly for a software engineer role. Two questions, both pretty standard delivery and adaptability territory. Nothing too surprising but worth prepping concrete stories for.
  • What specific habits or processes do you use to make sure a project stays on schedule?
  • Tell me about a time you had to change your approach mid-project to get it across the finish line.

“They wanted concrete mechanics, not just 'I communicate with stakeholders.' I talked about breaking work into smaller checkpoints and flagging blockers early, but I fumbled a bit when they pushed on what I actually do when a deadline starts slipping.”

Remitly·Software Engineer·Onsite - System Design / Architecture

Jun 2026
System design round at Remitly focused entirely on geospatial search. Pretty niche compared to the usual distributed systems stuff I'd prepped for, but it was a solid problem with a lot of moving parts once you dig in.
  • Given a set of geographic coordinates and a query point, design a system to return the k nearest locations. Walk through how you'd compute distances, what data structures or indexes you'd use, and how you'd handle scale.

“I started with Haversine for great-circle distance which was fine, but I fumbled a bit when they pushed on edge cases like antimeridian crossings.”
