I applied through an employee referral. I interviewed at Roblox
Interview
Like the others described, one online coding test (the same question as other people said - beware of the limitations in the tool - it's not very helpful for debugging), two onsites: first onsite consisted of 3~4 interviews with technical/behavioral questions, second onsite was CEO, VPs and directors trying to sell the company to the candidate. Both onsites did not pose any obvious red flags, the interviewers all seemed normal, nice, and smart (excluding one higher level person who did not care about listening to me at all, and gave an unprepared tech demo). During the application and interviews, when I mentioned my concern for compensation, the recruiter said that we will work something out that we both feel good about, which was misleading.

Reach out by recruiter, set up phone screen interview. 60 min coding interview. A leetcode style question with 3 follow up , overall experience is good got reject 2 weeks afterward.
The phone screen was surprisingly technical and lasted about 45 minutes, diving straight into system design. I was asked to design a leaderboard service, which caught me off guard at first. But as I started to outline my approach, I realized it was similar to a challenge I’d practiced on prachub.com just days before. The subsequent technical rounds were intense, focusing on DSA problems and scalability issues. In the end, I got an offer that I happily accepted, despite the difficulties I faced throughout the process.

Question 1
Design a leaderboard service that supports tens of millions of concurrent players. Cover top-K queries, neighbor-rank queries, partial sharding, and consistency tradeoffs.
Reached out by HR and chatted with a hiring manager. Mostly Behavioral questions such as why you want to work at roblox. The conversation was great and smooth. But they rejected me after a few days.
