I applied online. The process took 2 weeks. I interviewed at Roblox (San Francisco, CA) in Dec 2022
Interview
Technical Screen: I was asked a question related to trees. I reached an acceptable solution and had time at the end to ask questions. I was then ghosted by the recruiter.
Interview questions [1]
Question 1
Question related to using a tree to remove strings from a set where the string was a prefix of another string.
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.
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.
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
