I applied through an employee referral. The process took 5 months. I interviewed at Roblox (San Francisco, CA)
Interview
Up to the onsite things were a bit slow, but since the first onsite things were absolutely stellar. There are three rounds. 1. Phone (Coding), 2. Onsite (Coding, Coding, Systems Design, Behavioral), 3. Another Onsite (Systems Design, Systems Design, Behavioral).
Interview questions [1]
Question 1
Typical Silicon Valley type leetcode and systems design questions. The recruiter will be very transparent on what to expect for each of the rounds.
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.
