Real, anonymous reports from people who interviewed for Software Engineer at Lam Research, newest first and distilled into what to expect across the loop.
I went through a few rounds over roughly a month and a half, and the overall feel was tough-but-serious. The process included a technical portion where I worked through something anchored in real code—there was code analysis on sample code, and I also had to write a function in an existing codebase that called an external API and handled the response. On-site, the format tightened into multiple rounds that covered the common sweep: coding, system design, behavioral, and situational questions.
My loop was mostly panel-style and felt friendly on the surface. I went through three rounds with a mix of group members, managers, and senior directors. The vibe was generally comfortable, and I did get some casual conversation alongside the more formal parts.
