The phone screen was more intense than I'd anticipated, lasting about 45 minutes with a mix of behavioral and technical questions. They probed my understanding of system design, specifically challenging me to think through a notification delivery service. I felt prepared, thanks to the company-specific questions I found on PracHub that outlined similar scenarios. The final rounds focused heavily on the scalability and reliability of systems. After a series of interviews, I received an offer, which I happily accepted. Overall, it was a rigorous but rewarding experience.

Design LinkedIn's notification fan-out service that delivers post-engagement notifications (e.g. someone reacted to your post or commented on your article) to millions of subscribers in near real-time, including how you would handle 'hotspot' creators with millions of followers, deduplicate redundant notifications when many actions target the same content, and guarantee at-least-once delivery across regional failures.

Was greeted by a person who basically walked me around the office during my interview, did a couple of rounds with a group on a whiteboard solving a coding challenge, and one to solve a software architecture challenge. Had lunch onsite. And one round of interview with someone who wasn't technical.
