I applied online. The process took 2 weeks. I interviewed at Roblox (San Mateo, CA) in Oct 2023
Interview
Gave an online assessment which featured both traditional leetcode-style questions and a strange puzzle style question hosted on Roblox. Roblox started lagging during one of the puzzle activities, which caused me to do poorly. Did not advance past Online Assessment phase.

Question 1
Leetcode Medium-style Question followed by Roblox cognitive assessment
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.
