I applied online. The process took 4 weeks. I interviewed at Roblox (San Mateo, CA) in Feb 2025
Interview
Started with an online assessment (~ 3 hours). Recruiter follow-up call to schedule 2 technical interviews. The technical interviews were with two different Roblox engineers, 1 question each 45 mins. After completing the technical interviews, the recruiter will get back to you if you reached the next stage which is two behavioural interviews, 30 mins each, with different engineering managers/directors. All interview questions, technical and behavioural, were typical interview questions.
Interview questions [1]
Question 1
A situation where you had to convince someone of something (different approach, solution, etc.)
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.
