Background: around 5 years of experience, Backend (Java), Fintech.
Process so far
- Recruiter call. The recruiter shared prep docs and explained the loop: 4 rounds, 2 coding and 2 system design, with Leadership Principles (LPs) in every round. Very helpful.
- Day 1: two rounds, back to back.
Round 1: DSA (60 min, LiveCode, Senior SDE)
-
Problem 1: Next Greater Element (monotonic stack). https://leetcode.com/problems/next-greater-element-i/
-
Problem 2: Search in Rotated Sorted Array (modified binary search). https://leetcode.com/problems/search-in-rotated-sorted-array/
-
LiveCode is a plain shared editor: no compiler, no autocomplete.
-
LPs: Bias for Action (acting on an unclear, one-line requirement) and Dive Deep (debugging a production issue down to its root cause). Each had several follow-ups.
Round 2: LLD (60 min, Bluescape whiteboard)
- Question: "Design a package delivery system for an e-commerce company like Amazon. The system gets orders, packages are created for shipment, delivery agents deliver packages to customers, and the system tracks delivery status. Support assigning packages to agents, updating delivery status, and handling unsuccessful delivery attempts."
- Follow-ups: priority for Prime orders; assigning the highest-rated agent to Prime customers.
- LPs:
- Deliver Results
- Something unexpected and how I recovered
Will update with the remaining rounds and the result. Good luck, everyone!
