The interviewer was friendly. After brief introductions, I was asked to design a pagination API. I could call an external API that returns data for a specific page (e.g., input 3 to get the third page). The new API should allow users to input a number (e.g., 3...

I had one hour to complete three questions: two SQL questions and one Python question. The Python question was to invert a list of characters, keeping spaces in their original positions. For example, `['x', ' ', ' ', 'y']` should be inverted to `['y', ' ', ' '...
I had four rounds during my onsite interview. - **Round 1:** I was asked to implement transaction record pagination. The problem was straightforward. - **Round 2:** I was asked a commonly asked question which is simialr to Leetcode 981. I pretended to see the...
I applied online for several roles at Lyft (backend, mobile) and this was the only one that responded. My background wasn't a strong match. During the phone screen, I had to write code to implement an app. The HR representative sent a mock interview video befo...
During the phone screen, I solved LeetCode 155 in about 20 minutes. In the virtual onsite, I encountered a classic job scheduler problem. Another question involved designing a key-value database, which is similar to LeetCode 981. The system design portion focu...
I applied online and went through the following rounds: **Phone Screen:** Lasted 1 hour and 15 minutes. It was divided into two parts. The first part covered basic ML concepts, and the second part was a coding exercise. * **Part 1 (10-15 minutes):** I was give...
I interviewed with Lyft in early January 2025 for the Rider team in Toronto. The onsite interview consisted of a coding round, two system design rounds, and a behavioral round. **Round 1: Coding** The coding question was LeetCode 981. I was asked to implement...
The interview consisted of two parts: **Part 1:** I was given a table of 5 cross-validation test errors: ``` iterates test error -------------------------- 1 3.55 2 4.22 3 3.12 4 4.01 5 3.74 ``` Based on this, I was asked what the performance of the model woul...
I was asked one coding question (similar to LeetCode 91). I solved it using DFS, but it wasn't the most optimal solution. With the interviewer's hints, I thought of a DP approach but didn't implement it completely; I only wrote pseudo-code. Initially, the recr...
I interviewed for an L4 position. Here's a breakdown of my onsite experience: **Round 1: Coding** I was asked a variation of a problem involving finding all versions of something. The core solution involved using binary search. I finished 15 minutes early, and...
