I applied through the recruiter and took the Karat screening interview. The interviewer was quite professional and helpful. After discussing my experience, i was asked to attempt coding problems for 45 mins.
I solved the first one and almost finished coding for the second one but the interviewer asked me to stop as the time expired. She told me that all the progress till then will be taken into consideration but this kind of rigid time limit sounded ridiculous.
I gave them the feedback that it might result in subjective judgement about a good candidate. They responded that they will consider this for improvement. Waiting for the result now..

J'ai passé un entretien chez Roblox (San Mateo, CA)
Entretien
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.

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.
