I applied online. I interviewed at Roblox in Oct 2020
Interview
The first stage was completing a hackerrank with 3 questions in 90 min. After that, there were 2 45min technical interviews covering mostly standard data structure/algorithm style questions. The final round involved a 1 hr behavioral with a hiring manager and 45 min behavioral with a director. All the interviewers were incredibly friendly and did a terrific job of explaining the culture at Roblox. The offer came a couple weeks after the interviews.
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.
