Interview Process
The interview consisted of two coding challenges and a system design question. The first coding challenge involved creating a solution for a problem related to “Ling dance.” The second coding challenge required designing a global rate limiter that allows a maximum of n requests per second per client with zero latency. The interviewer prompted the candidate to reflect on the concepts of global limits and zero latency during this challenge. Following the coding challenges, there was a system design question focused on creating a vehicle heat map that displays the number of vehicles in real-time for the past 20 minutes and allows offline queries for up to one hour of historical data. The interview concluded with behavioral questions where the candidate was asked to introduce their project experience.
