10 LinkedIn Software Engineer (New Grad) Interview Questions (2026)
LinkedIn's new-grad SWE loop in 2026 is a recruiter screen, an online coding assessment, a technical phone screen, and a 4-5 round virtual onsite covering coding, host manager, system fundamentals, behavioral (LiHelp + Culture), and team match. LinkedIn is professional networking, jobs, and feed; graph and recommendation problems are common.

Loop overview
New-grad candidates report a 5-9 week timeline in 2026. Online assessment (2 problems, ~75 minutes), then a 1-hour phone screen. Onsite: two coding rounds, one system fundamentals or host-manager round, one Culture + LiHelp behavioral round. Stack is Java, Scala, Python, and TypeScript.
Behavioral (4)
Tell me about a time you helped a teammate succeed.
Frequently askedOutline
STAR. LinkedIn's LiHelp culture value is real. Pick a moment when you actively helped someone else level up — code review, debugging together, mentoring. Avoid framing where you took credit.
Why LinkedIn?
Frequently askedOutline
Tie to the professional graph, the mission of connecting opportunity, or a specific product (Jobs, Learning, Recruiter, Sales Navigator). Mention if LinkedIn helped you in your career. Be specific.
Describe a time you embraced a long-term mindset.
Frequently askedOutline
STAR. LinkedIn's culture values long-term thinking. Pick a moment when you chose a slower-but-better path over a quick fix. Show the tradeoff and the outcome.
Tell me about a time you transformed something through diversity of thought.
Occasionally askedOutline
STAR. LinkedIn's culture emphasizes inclusion. Pick a real moment when a diverse perspective changed the outcome. Show humility — recognize the contribution wasn't yours alone.
Coding (LeetCode patterns) (3)
Given a binary tree, return its zigzag level-order traversal.
Occasionally askedOutline
BFS by level, alternate direction (deque). Append left-to-right on even levels, right-to-left on odd. O(N) time and space.
Implement a function that returns whether a string is a valid number (handle integers, decimals, exponents).
Occasionally askedOutline
State machine over chars: sign, digit, decimal point, exponent. Or regex. Walk through edge cases: '-1.5e+3', '.5', '1.', 'abc'. Tricky to get right; practice.
Given a graph, return the number of connected components.
Occasionally askedOutline
DFS or union-find. Iterate nodes, start a DFS from each unvisited. Count starts. O(V + E). Walk through with a small graph.
Technical (3)
Given a graph of LinkedIn connections, find the shortest connection path between two members (degrees of separation).
Frequently askedOutline
BFS from one user. Track visited and distance. Stop when target reached. O(V + E) worst case. For LinkedIn's scale, bidirectional BFS (search from both ends, meet in middle) is much faster. Discuss this. Domain-perfect.
Given a list of job postings with required skills, return jobs that match a candidate's skill set.
Frequently askedOutline
For each job, check skill-set overlap. Score by intersection size or weighted by skill rarity. O(N * S) where S is average skills per job. Discuss inverted index (skill → jobs) for faster lookup at scale.
Implement a function that returns the K most relevant feed items given user interests.
Frequently askedOutline
Score each item by overlap of (item topics ∩ user interests). Use heap of size K. O(N log K). Discuss ranking signals beyond overlap: recency decay, engagement signals, diversity (don't show 5 items from same author).
LinkedIn interview tips
- LinkedIn is a graph-and-recommendation product. Brush up on BFS, DFS, bidirectional search, and inverted indexes.
- Behavioral rounds reference LiHelp + Culture explicitly. Read LinkedIn's values page before the loop.
- Stack is Java and Scala heavy on backend. Coding rounds are language-agnostic.
- LinkedIn's engineering blog has solid content (Pegasus, Brooklin, Datahub). Read one before the loop.
- Compensation per Levels.fyi 2026 is solid for Sunnyvale CA new-grad. Equity has 4-year vest with 1-year cliff.

HackerRank is a browser-based coding-assessment platform that tests algorithms, SQL, and role-specific skills, and records every keystroke, paste, and tab-focus change inside its own tab. As of the 2026 hiring cycle it is still the volume leader in first-round technical screens. The way through it is recognizing the problem shapes it keeps asking, under a timer, and taking the test yourself.
Karat Technical Interview Guide 2026: How the Third-Party Loop Actually Works
Karat is technical-interview-as-a-service. Karat-employed engineers run the technical loop for the hiring company in Karat's own recorded video and coding environment. The dynamic is different from an in-house interview: the interviewer is a contractor, not a future teammate, the rubric is fixed, the session is recorded for asynchronous review, and the hiring team's engineers watch the playback a day later. This guide is the practical map of how that loop works in 2026 and how to prepare for it.
