I applied through other source. The process took 2 months. I interviewed at Roblox
Interview
I applied and was sent a link to their applicant site. It was a coding test, followed by some performance/personality tests via a Roblox game. The coding tests were done through HackerRank while the perfomance/critical thinking test was in their Roblox platform.
Interview questions [1]
Question 1
They asked a lot of questions on the coding test similar to LeetCode. The personality/critical thinking tests were a game in Roblox where you had to try and optimize a system in a given amount of time.
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
