Lyft·Product Manager·Onsite - Product Sense / Strategy

Jun 2026
Lyft product sense round, one question about scheduled rides and how to give drivers more control over them. Pretty focused session, no fluff.
  • How would you design a feature that lets Lyft drivers choose from a pool of scheduled rides rather than just having them assigned automatically?

“Took me a second to get oriented because I kept thinking about it from the rider side first.”

Lyft·Software Engineer·Onsite - Product Sense / Strategy

Jun 2026
Lyft product analytics interview with a classic metric investigation prompt. Not a lot of context to go on but the question itself was meaty enough to fill the time.
  • Rider cancellations at Lyft have gone up by 5%. Walk through how you'd investigate what caused it.

“My first instinct was to jump straight into supply-side explanations like driver ETAs getting worse, but I caught myself and slowed down to segment the 5% first.”

Lyft·Product Manager·Onsite - Product Sense / Strategy

Jun 2026
Lyft PM interview with a single open-ended product design question about building a food startup from scratch. Pretty sparse on details but the question itself has some meat to it.
  • Design a new food startup from the ground up.

“This kind of question looks easy and then you open your mouth and realize you have no idea where to start.”

Lyft·AI Engineer·Onsite - System Design / Architecture

Jun 2026
System design round at Lyft for an AI Engineer role, basically one big question about building an internal HR Q&A platform on top of company docs. Dense question with a lot of moving parts, felt like they wanted to see how far you could go end-to-end.
  • Design an AI platform that lets employees ask natural-language questions about internal HR documentation. Walk through the full pipeline from document ingestion to answer generation, including retrieval, access control, PII handling, and evaluation.

“This one sprawled in every direction.”

Lyft·Product Manager·Onsite - Product Sense / Strategy

Jun 2026
Lyft PM interview, one question in and it was a product design prompt that sounds deceptively simple until you actually try to answer it.
  • How would you design a Lyft product specifically for children?

“My first instinct was to just say 'add parental controls and a kid-friendly UI' which is...”

Lyft·Product Manager·Onsite - Product Sense / Strategy

Jul 2026
Lyft product interview, one open-ended question about launching a new transportation mode. Pretty short session but the question had a lot of surface area and I wasn't totally sure where to take it.
  • Lyft wants to launch a new mode of transportation (assume bikes and scooters don't exist yet). What would you build and why?

“I spent probably too long on the setup before getting to an actual recommendation.”

Lyft·Software Engineer·Onsite - System Design / Architecture

Jul 2026
Lyft system design round, one big sprawling question about building a distributed web crawler from scratch. They really wanted to see how you'd think through scale and failure modes across a thousand machines, not just the happy path.
  • Design a distributed web crawler that starts from a single seed URL and scales to 1,000 worker nodes. Cover URL partitioning and deduplication, politeness policies, prioritization, retry logic, content deduplication, failure handling, coordination, backpressure, fetch semantics, storage, monitoring, and safety controls. Also define APIs and data models for enqueueing URLs, checking status, and retrieving results.

“This question is basically a whole system design interview wrapped into one prompt.”

Lyft·Data Scientist·Technical Phone Screen

Jul 2026
Lyft data science interview with a meaty two-part case: diagnose a sudden metric change, then design an A/B test around the fix. The kind of question that sounds manageable until you're actually in it and realize how many moving parts there are.
  • A core business metric suddenly spikes or drops. Walk through how you'd systematically investigate the root cause.
  • Outline the key steps, assumptions, and success criteria for designing and analyzing an A/B test to validate a proposed fix for that metric issue.

“I started with time-based decomposition, which felt right, but I jumped to conclusions too fast about what segment was responsible before actually checking the data.”

Lyft·Software Engineer·Take-home Assignment

Jul 2026
Lyft sent over a take-home where instead of writing code you're writing back to a PM who's left comments all over a doc. Weird format, kind of refreshing, but also way harder to prepare for than a standard coding screen.
  • Given a document with a Product Manager's comments, questions, and pushback on technical decisions, how do you respond in writing to clarify your reasoning, address concerns, and propose alternatives where needed?

“This is not a question you can grind leetcode for.”

Lyft·Product Manager·Onsite - Product Sense / Strategy

Jul 2026
A product sense question from Lyft focused on launching a self-driving ride-share pilot in Palo Alto. Pretty scoped scenario but there's more going on under the surface than it first appears.
  • You're a PM at Lyft launching a self-driving ride-share service in Palo Alto. Routes are already safe and pre-programmed. How do you select roughly 10 pickup and drop-off locations?

“I went straight to demand density and started rattling off places like Caltrain stations and the Stanford campus.”
