I applied online. The process took 2 months. I interviewed at Tesla (Lathrop, CA) in Mar 2026
Interview
The interview process consisted of an initial recruiter screening followed by a technical panel interview with multiple engineers from manufacturing and process teams. The discussion focused heavily on real-world problem solving, data-driven decision making, and manufacturing concepts such as OEE, process optimization, and root cause analysis. I was asked to walk through past projects in detail, especially those involving throughput improvement, yield optimization, and cross-functional collaboration. The panel emphasized practical thinking, ownership, and the ability to scale solutions for high-volume production environments. Behavioral questions were also included to assess teamwork and adaptability in fast-paced settings.
