Lyft Interview Loops
Lyft runs two data science tracks, Decisions and Algorithms, and the loop has the same shape for both. A recruiter call, a one-hour technical phone screen, and a virtual onsite of four to six interviews. The phone screen has no coding. It's probability, experiment design and business questions about the marketplace, and most people who get a no get it there. The onsite adds a business case, a technical case, live coding and a conversation about your experience. There's no take-home. Lyft's questions are about one market with two sides. Drivers and riders share it, so a test for drivers moves riders too, and a coupon that lifts rides costs margin. Practice reasoning through those trade-offs out loud, with numbers.
