I applied online. The process took 3 weeks. I interviewed at Roblox (San Mateo, CA) in Sep 2024
Interview
Multi-part OA, first round two back to back technical interviews of leetcode medium to hard. Aced first part and solved second but didn't get past. Not sure what they are looking for from there.
OA consisted of several games, usual optimization and car building game. The next round was standard technical with 2 interviews that are 45 minutes, leetcode style. The final round was a behavioral which is pretty standard.
First is online assessment. Takes around 3 hours to complete. If you pass, then you have 2 techincal interviews. After that, you get a behave interview. Im pretty sure thats the last interview
