Took an OA. Pretty difficult leetcode style questions and some games (Roblox games and psychology based games to determine personality traits). I did not get through the initial online assessment.
Difficult interview
Application
I applied online. I interviewed at Roblox in Feb 2021
Interview
Before you talk to anyone you take a 90 minute online assessment.
Any language you want. The test is three somewhat difficult problems.
Afterwards you might get an email describing the next steps in the process.
Interview questions [1]
Question 1
General HackerRank interview questions. All of them would take some time, definitely more challenging than a FizzBuzz question.
One standard hr phone call then one 60 min phone screen. Nothing out of the ordinary. Phone screen was done on codesignal where you could see code compile and run
Interview consisted of two leetcode style questions and two "games" that tested problem solving and optimization. Coding questions were of medium/hard difficulty. The games were difficult as the instructions given were terrible and unintuitive.
