I applied through a recruiter. The process took 1 week. I interviewed at LinkedIn (San Jose, CA) in Apr 2016
Interview
After phone conversation with recruiter, I had phone interview in following week. Interviewer called me on time. But I was given the wrong interviewer. First he went through my experience. and then gave two coding problems. I felt he did not prepare for his interview problems well. We spent lots of time on the time complexity. Also it seems that he wanted the answer he wanted, and not realized there are several solutions.
Interview questions [1]
Question 1
nested list sum; design algorithm to add integer and check if there is two integers which sum up to the targeted sum.
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.

Question 1
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.

Interview
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.
