Interview Process
The interview began with a 15-minute behavioral questions (BQ) segment, which consisted of straightforward one-on-one questions without follow-up inquiries. This part was not difficult. It was followed by a 30-minute coding session that was not in the typical LeetCode style but instead focused on an ambiguous object-oriented programming (OOP) problem. The task was to create a matching system for Amazon packages and Amazon lockers. Candidates were required to define the API, including the request and response formats, while considering high availability and error handling. The interview primarily assessed the ability to navigate ambiguity, OOP concepts, and included some data structures and algorithms (DSA) discussions.
During the high availability and error handling discussion, I focused on how to handle multiple package requests for lockers simultaneously. The main solution proposed involved splitting the process into two functions: reserve and commit. For error handling, I modified the return type to StatusOr.
