J'ai postulé en ligne. Le processus a pris 3 semaines. J'ai passé un entretien chez LinkedIn (San Francisco, CA) en oct. 2018
Entretien
I applied online and also with a recruiter. Standard process - set up a phone screening a couple of weeks out. The interviewer was definitely not the one listed in the email (possibly last minute replacement) and he must have been sitting in an open area at first; I had to mention the heavy background noise twice (I could hear voices, though not exact words, before he made his first adjustment).
Because of the level I was asked a lot of platform (iOS) questions, primarily around threading, in a rapid-fire manner. I know I did well on the algorithms (saw a more complicated version of one of them before) and even had time at the end to discuss, but not code, a variant on one question. However, I supposedly did not answer the platform/threading questions fast enough so the hiring committee (for a phone screen) declined to invite me for an onsite. Very likely I would not have moved on regardless of the background noise, but it didn't help.
NestedInteger weight sum - given a class with callable methods isInteger, getInteger, and getList get the weighted sum, e.g. {1,{4,{6}}} => 1 + (4*2) + (6*3) = 27
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.
Questions d'entretien [1]
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.

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.
