How important is the behavioural round at LinkedIn?

Very — distinctively, LinkedIn weights the behavioural/values round heavily and treats it as a genuine gate. Strong coding cannot rescue a weak values read, so prepare STAR stories mapped to its actual values.

What coding patterns does LinkedIn favour?

Medium-to-hard DSA with a known emphasis on tries/prefix problems, graphs (BFS/DFS), trees and heaps/top-K. Interviewers value clean, working, well-tested code plus a follow-up optimization.

What system design does LinkedIn ask?

Prompts flavoured by its domain — a feed, the connections/social graph and "people you may know", search/typeahead, or messaging — with sharding, caching and consistency/latency trade-offs. Depth scales with seniority.

The LinkedIn interview, in brief

LinkedIn is the world's largest professional-networking platform (a Microsoft subsidiary since 2016, but it hires and interviews under its own process and engineering culture). It runs a large, product-focused engineering org spanning feed/graph, search, messaging, ads and data/ML at hundreds-of-millions-of-members scale. Engineers target it for high-scale distributed-systems work and a strong, values-driven culture.

A typical funnel is a recruiter screen, a technical phone screen (one or two coding problems on a shared editor), and a virtual/on-site loop of four to five interviews: two coding rounds, one or two system-design rounds (scaling with seniority), and at least one dedicated behavioural/values round. Distinctively, LinkedIn weights the behavioural round heavily and ties it to its values — a genuine gate.

Interview rounds

1. Recruiter screen 15–30 min

Background, motivation, logistics and a light values read.
2. Technical phone screen 45–60 min · 1–2 problems

Data structures & algorithms on a shared editor, with complexity analysis.
3. Coding rounds ~2 rounds · medium–hard

Arrays/strings, tries/prefix, graphs/BFS-DFS, trees, heaps/top-K, sliding window; clean code plus a follow-up optimization.
4. System design 1–2 rounds · scales with seniority

Feed, connections graph / "people you may know", search/typeahead, or messaging — data model, sharding, caching, consistency.
5. Behavioural / values Heavily weighted · STAR

Mapped to LinkedIn's values; a genuine gate that can sink an otherwise strong loop.

System design

Expected for mid-level and above (lightweight LLD may appear for new grads). LinkedIn's domain drives the prompts: designing a news/activity feed, the connections/social graph and "people you may know", search/typeahead, or messaging/notifications — with data modelling, sharding, caching and consistency/latency trade-offs. Senior candidates drive API design, data modelling, bottleneck analysis and scaling end-to-end.

Behavioural round

LinkedIn's behavioural round is unusually prominent and maps to its published values — Members First, Relationships Matter, Be Open Honest and Constructive, Demand Excellence, Take Intelligent Risks, and Act Like an Owner. Expect STAR-format questions on ownership, prioritization, cross-team collaboration, handling conflict, mentorship and "why LinkedIn". Strong technical performance can still be sunk by a weak values read.

Representative question categories

Patterns in LinkedIn’s style — not verbatim proprietary questions.

Tries / prefix — Autocomplete-style prefix-string problems.
Graphs — BFS/DFS traversal and connectivity problems.
Trees & heaps — Tree manipulation and top-K / interval-style problems.
Feed & graph design — Design a feed, the connections graph, or "people you may know" at scale.
Search design — Design search / typeahead for a large member base.
LinkedIn values — A time you acted like an owner or influenced without authority.

How to prepare

Do

Grind the LinkedIn-tagged LeetCode list; drill tries, graphs and trees specifically.
Treat the behavioural round as a real gate — prepare four to six STAR stories mapped to the actual values.
Narrate trade-offs and test your code on edge cases before saying "done", then drive the optimization.
For design, anchor answers in LinkedIn's own domain (feed/graph/search) and quantify scale.

Avoid

Underpreparing the behavioural round — strong coders get rejected on weak or generic values answers.
Producing brute-force code and not driving the optimization/complexity discussion.
In system design, jumping to components without clarifying scale, data model and requirements.
Not tailoring "why LinkedIn" or ignoring the members-first framing.

Who can apply

The public IC ladder runs roughly Software Engineer (entry) → Senior Software Engineer → Staff → Senior Staff → Principal, then Distinguished/Fellow. New-grad and experienced tracks both exist; internships feed the new-grad pipeline. Exact level codes are not officially published. Higher levels weight system design and scope more heavily.
