Interview process was somewhat unprofessional. Unformatted emails and a cold interview with random tech trivia questions that you seldom use outside of university. Worse is they are only tangentially related to the position. Observed several red flags as an experienced engineer. I would not recommend this company to candidates. I can only imagine what the work environment is like if this is what the interview process is like.
