      Difficult interview

      Application

      I applied online. The process took 4 weeks. I interviewed at Tesla

      Interview

      Had three rounds of interviews which consisted of meeting with a panel of other engineers on the same team. Most asked surface level questions about my work history and experience/education in this particular field. The last couple of engineers asked very pointed questions and were definitely gauging my ability to interpret chemical data and to solve problems from first principles.
