I applied online. The process took 3 weeks. I interviewed at Roblox (San Mateo, CA) in Oct 2023
Interview
Started with a unique OA including 2 coding questions and 2 Roblox Games. The first game was optimizing a factory profit, the second was building cars to cross different terrains. After OA, there was a technical interview which was 2 45 minute coding problems. Problems were not very difficult, asked to analyze runtime after and how to improve that. Next round was 2 30 minute behavioral interviews, very standard. Then received final response in about a week. Everyone I interviewed with and my hiring manager were very nice and helpful!
Interview questions [1]
Question 1
Time when there was diversity within a team and how you overcame it, time when you had to learn a new skill immediately
I interviewed twice for this position. I passed the online OAs which included four tests, and was invited to a technical interview online. The first interview was two reasonable LC easy-mediums which had two parts each. However, I could not complete the second part of the second question. When I re-interviewed with them two months later to try again, the question bank got way more difficult, involving LC med-hards. I could not complete the questions the second time around, and I imagine you would have to basically memorize these answers to be able to do them on the interview in an hour each.
First part of the interview was 2 different cognitive assessment, both hosted as Roblox games. First involved trying different combinations of car assemblies to pass different obstacle courses. Second involved optimizing a factory production line.
The second part of the interview takes you through a bunch of different workplace situations, and asks you to assess the least and most effective ways to address them from a list of options.
And finally, you are asked to complete two leetcode like questions on CodeSignal. One was about medium and one was hard.

Interview
OA - Roblox games, and regular leetcode style questions
Technical Round - Leetcode style questions. Didnt get pas this because I had an offer elsewhere, but Medium to Hard style questions
