I applied through an employee referral. I interviewed at Roblox (San Mateo, CA) in Sep 2025
Interview
The interview process was one of the most transparent and well-organized I’ve had so far. From the very beginning, i knew how many stages there will be, what the expectations were, and what the role involved.
The coordination was excellent - the recruiting team was very responsive and next steps were scheduled within 1 day. I always knew how to prepare and what was being evaluated during each step.
Another highlight was the people. Every I talked to was very professional, friendly, and genuinely pleasant to talk to.
Interview questions [1]
Question 1
The coding task was particularly interesting, as it was connected to real-world scenarios. In my case, it involved match pattern detection on a field.
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.
