      Difficult interview

      Application

      I applied online. The process took 7 weeks. I interviewed at Mainspring Energy (Menlo Park, CA) in May 2024

      Interview

      The interview process consisted of four stages, starting with an informational interview with HR to assess role fit and discuss key skills like Python and C++. The second stage involved behavioral and technical questions with the hiring manager, focusing on past projects and interpersonal challenges. The third stage was a take-home assessment requiring analysis of PID controllers, programming optimization, and test plan creation. The final stage included an in-depth technical discussion and a programming assessment in C++, covering topics like state variables, state machines, and PID controllers, along with behavioral questions about project challenges and team dynamics.
