Interview Process
The interview consisted of several rounds, including coding, AI coding, behavioral questions, technical communication, and system design. The candidate faced a coding challenge where they had to solve a problem related to a summation that was modified to a product, for which they only provided a brute force solution. In the AI coding segment, the candidate discussed their approach to implementing an LRU cache, where they articulated their thought process and had the AI generate the code, followed by dry running a few test cases and addressing multithreading concerns. The behavioral questions focused on previous impactful projects, requiring the candidate to explain and illustrate their work on a whiteboard. In the system design round, the candidate was asked to design an exception monitoring system that displays the top K exceptions to on-call personnel. The candidate struggled with this question, particularly around how to collect exceptions and the naming conventions for database schema columns.
