Linkedin Coding & Algorithms Interview Questions

LinkedIn Coding & Algorithms interview questions typically focus on clean, production-minded problem solving rather than trick puzzles. Interviews evaluate algorithmic thinking, data-structure choice, complexity trade‑offs, and communication: you’ll be expected to write correct, readable code in a shared editor (CoderPad or similar), explain time/space complexity, and walk through edge cases and tests. Expect an initial 45–60 minute technical screen with one or two coding problems and a later virtual onsite with multiple rounds that probe depth, follow-up optimizations, and your ability to iterate under feedback. For effective interview preparation, practice core patterns (two pointers, sliding window, DFS/BFS, heaps, dynamic programming) and rehearse explaining your thought process aloud while coding. Time-boxed mock interviews replicate pressure and reveal gaps; review common pitfalls like off‑by‑one errors, null handling, and inefficient data structures. Emphasize clear variable names, incremental testing, and trade‑off discussion during the interview—these signal seniority and team fit as much as a correct final solution.
