I had an initial interview at my university. I really liked the people who were interviewing me. By that time, I had interviewed with a ton of companies, so it was fairly easy. They asked me standard interview questions and walked through my resume. They emphasized that as a small company I would wear a lot of hats so I would get a lot of experience. Also, it was not as cut-throat as bigger companies. I was called back for an on-site interview. I was taken to each department (R&D, EHS, and Technology) and interviewed by leadership there.
