LinkedIn’s engineering interviews reward more than just correct answers—they test how you write scalable code, break down complex systems, and communicate clearly under time pressure. These questions are built to mirror real interview themes at LinkedIn, from traversing massive connection graphs to processing millions of data events with low latency. You’ll solve coding problems grounded in practical use cases: designing features around LinkedIn’s graph, optimizing performance for large-scale data operations, and maintaining clarity in logic even under constraints. This isn’t just a prep set; it’s a simulation of how LinkedIn thinks about engineering at scale. Every question gives you the chance to practice coding while explaining trade-offs, edge cases, and design decisions, just like you would in a real LinkedIn technical screen.

"You guys are the gold standard of crash-courses... Narrow enough that it doesn't need years of study or a full blown book to get the gist, but broad enough that an afternoon of Googling doesn't cut it."
