J'ai postulé en ligne. Le processus a pris 6 semaines. J'ai passé un entretien chez LinkedIn en déc. 2024
Entretien
[Coding round 1]
2 questions. 1 Easy and 1 DP
DP question was unnecessarily hard, required 2D DP with bit masking. Interviewer was fairly new, had ~3y experience and was dead set on the optimal solution for the hard DP problem. If you're interviewing with Linkedin make sure to blindly memorize leetcode solutions in case you get a junior interviewer.
Questions d'entretien [1]
Question 1
1 - Given a boolean matrix, find the influencer. Influencer is a person who does not follow anyone, but is followed by everyone else. a[i][j] -> i follows j , a[i][i] - is guaranteed to be false
2 - Given an array of random integers return if this array can be divided into k subsets where sum of each subset is equal.
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.

J'ai postulé via un recruteur. J'ai passé un entretien chez LinkedIn (San Francisco, CA)
Entretien
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.
