Nubank·Product Manager·Onsite - Product Sense / Strategy

Jun 2026
Interviewed for a PM role at Nubank and got hit with a product sense question about improving a restaurant. Pretty classic case-style prompt but it still made me think harder than I expected.
  • How would you improve your favorite restaurant?

“I picked a place I actually go to regularly, which helped, but I spent too long setting up context about the restaurant itself before getting to any real insight.”

PM interview at Nubank with a product metrics question framed around Uber Lite. Pretty focused session, just the one scenario but it went deep fast.
  • You're a PM responsible for launching a lightweight, simplified version of a ride-hailing app. How would you define and measure success for that launch?

“I went straight to activation and ride completion rates, which felt safe, but the follow-up pushed me on whether I was thinking about the right user segment at all.”

PM interview at Nubank with a product strategy question about defining success for Airbnb Experiences. Short and focused, just the one question from what I can tell.
  • How would you define success for Airbnb's Experiences product?

“This type of question always trips me up because it sounds like a metrics question but it's really asking you to think about what the product is even trying to do first.”

PM interview at Nubank with a product expansion case. One question, fairly open-ended, the kind where you can go a dozen directions and second-guess every one of them afterward.
  • You are a PM at a ride-sharing company. How would you expand the product to better serve elderly users?

“I went straight into user empathy mode and started listing pain points for older adults: small text, confusing app flows, trust issues with strangers, physical difficulty getting in and out of cars.”

PM product sense question for Nubank, framed around Instagram. One question, open-ended, and I spent probably too long trying to be clever instead of just being structured.
  • You are the PM for Instagram. How would you improve friend group dynamics and the way friends socialize on the platform?

“I went down a rabbit hole about group features and ended up pitching something like shared activity feeds between close friends.”

Nubank·Software Engineer·Onsite - System Design / Architecture

Jun 2026
System design round at Nubank for a software engineering role. The whole thing was centered on one big problem: designing a chargeback ingestion and export system for a bank that ships CSV files to Mastercard over FTP four times a day. Dense question with a lot of moving parts.
  • Design a chargeback ingestion and export system for a bank that receives transaction records from internal systems, validates and stores them, then generates a CSV file and transfers it to Mastercard over FTP four times per day. Walk through the architecture, data model, batching strategy, reliability and idempotency guarantees, error handling, monitoring, and security.
  • A scheduled batch's FTP upload fails all retries and misses its delivery window. What state is the batch in, what gets alerted, and how does the next run avoid double-sending or skipping those records?
  • The upload to Mastercard completes successfully but your process crashes before it can record the success in your own database. On the next retry, how do you determine the file already arrived so you don't cause the partner to process it twice?
  • Mastercard's acknowledgment file shows 3% of a batch was rejected due to a bad reason code. How do you reconcile this: how do those records get re-validated, re-queued, and exported without re-sending the accepted 97%?
  • Daily volume grows 10x. Which components hit bottlenecks first, and how would you scale ingestion, validation, CSV generation, and transfer independently?

“I started with the architecture split and that was the right call.”

May 2026
PM interview at Nubank with a product sense case about improving the in-store experience at Pão de Açúcar supermarkets. Pretty open-ended, which I wasn't fully prepared for coming from a fintech context.
  • You're a PM for a major supermarket chain. How would you improve the in-store customer experience?

“I spent too long trying to segment users and never really landed on a crisp problem to solve.”

May 2026
Interviewed for a business analyst role at Nubank, got a product strategy case about whether a bank should build out an investment brokerage feature inside its credit card portal. Pretty open-ended, which I wasn't fully prepared for.
  • A bank is thinking about adding an investment brokerage service to its existing credit card portal. How would you evaluate whether this is worth building?

“I went straight into market sizing and kind of lost the thread for a bit.”

May 2026
PM interview at Nubank, one question about defining success for a logistics product in Brazil. Short but made me think harder than expected about what 'success' even means in a two-sided delivery context.
  • You're the PM for a logistics delivery product in Brazil. How would you define success for it?

“I jumped straight to metrics and listed things like on-time delivery rate and order volume, which felt fine but kind of shallow in retrospect.”

Apr 2026
PM interview at Nubank, product sense round focused on metrics for a lightweight app product. Single question, pretty open-ended, felt like it could go a dozen directions at once.
  • You're the PM for Uber Lite in a city of your choice. How would you define and measure success for the product?

“I picked a city pretty fast (went with Lagos, figuring emerging market context would make the 'Lite' angle more defensible) but then I spent way too long on activation metrics and kind of forgot to anchor on why Lite exists in the first place.”
