Solicité el puesto a través de un captador. El proceso duró 4 semanas. Acudí a una entrevista en Roblox (San Mateo, CA) en abr 2019
Entrevista
Recruiter reached out to me and set up a call with the director of this team.
I had a good discussion and we moved on to a take home assignment.
After a couple of iterations, I was OK'd and was invited on site.
There would be 7 rounds in total each 40-45 minutes. The team was fantastic to talk to. I loved having "productive discussions" rather being an anxious interviewee sitting on the opposite end of the table dodging fires ! Loved all the traditional networking, multi threading, data structures and algorithm challenges. I did pretty well on most of them except for a couple of rounds. I knew I wouldn't make the cut. It was fine, I could get better and I definitely will one day ! I had a small ray of hope that I would still get the offer since the director had liked my solution from the take home and he did find some of my background and projects impressive and felt I could fit in well. Maybe some another day !

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.

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.
