LinkedIn Interview Guide & Preparation
LinkedIn (a Microsoft subsidiary) runs a structured interview process that blends Microsoft-style cultural assessment with strong technical evaluation. Interviews cover standard coding, system design for social/professional networking at scale, and behavioral questions around LinkedIn's culture of transformation, integrity, and member-first thinking.
Interview Process
