I applied through a recruiter. The process took 1 week. I interviewed at LinkedIn in Jul 2015
Interview
Contacted by their recruiter. Next day had a call with her, and within 24 hours they scheduled a phone interview for the next week. Smooth and clear, no hiccups.
Phone interview was with one of their junior SWE, he was very nice and polite. We briefly talked about each others' past and current projects and went straight to the coding. Was not that hard after all, I just did not have a practice of that sort of interactive coding. The guy, again, was polite, few times gave me some small hints. At the end he confirmed that I did it correct.
Recruiter contacted me next morning and asked for another phone call with more senior team members. Going to do it next week.
Interview questions [1]
Question 1
Task was for using different data structures in Java Collections framework.
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.
I applied online. I interviewed at LinkedIn (San Francisco, CA) in Mar 2026

Questions - Regular Medium level question, string manipulation

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.
