What is the recruitment process at LinkedIn?

The typical LinkedIn recruitment process has 4 stages: Recruiter screen and coding phone screen → Onsite coding rounds on DSA → System-design round on a graph or feed problem → Hiring-manager and values round, then offer.

What are the interview rounds at LinkedIn?

LinkedIn typically conducts 4 interview rounds: Round 1 (45 min): coding phone screen on data structures and algorithms.; Round 2-3 (45 min each): onsite coding rounds.; Round 4 (45-60 min): system-design round on graph or feed problems.; Round 5 (45 min): hiring-manager round on ownership and collaboration..

What system-design questions does LinkedIn ask?

Design 'People You May Know' connection recommendations, 'who viewed your profile' with counts, and a feed blending posts, jobs, and recommendations, all on top of the social graph.

How do I design 'People You May Know'?

Store the connection graph, compute second-degree candidates offline in batch, rank them by mutual connections and other signals, and serve the precomputed list online for low latency.

How does LinkedIn handle write-heavy features like profile views?

Ingest view events through a streaming pipeline, aggregate counts asynchronously, and separate the write path from the low-latency read path that renders the recent-viewers list.

LinkedIn System Design Interview Questions 2026

LinkedIn's system-design rounds revolve around its social graph and professional feed: design 'People You May Know', design 'who viewed your profile', design a feed blending posts, jobs, and recommendations.

Practice with AI voice feedback 12 questions · System Design · 2 sessions free

In 2026 strong candidates lead with graph storage and second-degree traversal, decide what to precompute offline versus serve online, and handle write-heavy event streams like profile views. Interviewers probe how you rank and dedupe heterogeneous content and how you keep latency low while the graph grows. Vague 'use a graph database and it scales' answers get taken apart in the follow-ups.
