I applied online. The process took 3 weeks. I interviewed at Roblox in Dec 2022
Interview
It was an interactive virtual environment that involved analyzing patterns of animal populations for example, predicting which ones would grow, and how to manipulate their environments in different ways such as soil, altitude, etc.
Interview questions [1]
Question 1
Look at the following populations of wolves in the game below and predict their growth for the next 10 years
Took an OA. Pretty difficult leetcode style questions and some games (Roblox games and psychology based games to determine personality traits). I did not get through the initial online assessment.
One standard hr phone call then one 60 min phone screen. Nothing out of the ordinary. Phone screen was done on codesignal where you could see code compile and run
Interview consisted of two leetcode style questions and two "games" that tested problem solving and optimization. Coding questions were of medium/hard difficulty. The games were difficult as the instructions given were terrible and unintuitive.
