I applied through a recruiter. I interviewed at LinkedIn in Mar 2016
Interview
Very negative experience, the interviewer was late for 6 minutes and didn't apology for the delay. It was clear from the beginning that he is in a hurry and the interview is not interesting for him. He didn't qute well understand the solutions that I suggested and we spend quite a long time just to explain how I'm going to solve it. Maybe I didn't explain it well, but I'm sure it was because he had no interest for the interview and didn't follow what I'm talking about. As the result I spent a pretty long time for a medium coding question. In the middle of the interview the interviewer disappeared for 5 minutes (!!) and I talked with no one. Eventually I solved both problems and suggested optimizations, but looks like the time and overall interviewer's negative were critical factors and as expected I got rejected. I didn't have such unprofessional phone interview for a long time.
Interview questions [1]
Question 1
Standard questions from leetcode, they don't expect you to think, they expect you to _know_. Even the recruiters tell imagine the interview as kind of college exam.
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.
