Interview Process
I had two interviews at Roblox, both were technical phone screens. The first interview focused on a coding problem related to rate limiting. The interviewer was very friendly and asked me to explain my thought process as I worked through the problem. I was asked to implement a function that limits the number of actions a user can take within a given time frame. I started by explaining a basic brute force approach, and then the interviewer pushed me to optimize it.
The second interview was also a coding problem but this time it involved designing a simple traffic system simulation. I used a few data structures to represent the vehicles and their movements. The interviewer asked me to explain my reasons for using those data structures in detail.
