I applied online. I interviewed at Roblox (San Mateo, CA) in Aug 2020
Interview
1. Took a standard 3-question HackerRank OA
2. Did virtual on-site about 2-3 weeks later
3. Did virtual final round 2-3 weeks after the on-site
The final round had a bar raiser round added in because they interviewed way too many people in the second round.
Took SIX WEEKS to get a reply with a final decision after two of my deadlines had expired. What kind of company does this? I had to contact the head of university recruiting through Linkedin InMail to only get an autorejection the same day.
Interview questions [1]
Question 1
[Coding question] Given an NxN Sudoku board, determine if the current configuration is valid or not.
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.
