Online assessment that includes a code signal assessment, which is two problems of medium-hard difficulty. Afterwards, using the roblox app itself to design factories and build cars that pass a maze.
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.
J'ai passé un entretien chez Roblox (San Mateo, CA)
Entretien
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.
