I applied through college or university. The process took 1 week. I interviewed at Roblox (Pittsburgh, PA) in Oct 2014
Interview
This is an internship and it was the first interview on the phone, but it includes both general and technical questions. I was not that good at the technical questions. And about one week later they sent me an email telling me I was lack of some skills they need.
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.
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.
