I applied online. The process took 3 days. I interviewed at Roblox (San Mateo, CA) in Sept 2022
Interview
Section 1 - Play a few video games where you have to solve strategic problems.
Section 2 - Solve three data structure problems similar to leetcode
Section 3 - Technical interview
Interview questions [1]
Question 1
Hashtable problem, you can choose between Python3, Java, and don't remember the other
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.
