LiquiGlide interview questions

First met with a representative (another engineer) on-campus for a brief, 30 minute interview. The followup was about two and a half hours with an account manager, and two other engineers. The account manager asked more general questions about the role I could see myself playing in the company. The engineers asked more technical questions, but not in too much detail. Understanding their product beforehand is definitely beneficial.

The company is operating as a startup, so their hiring and HR practices are nowhere as smooth or refined as established organizations. One of their current employees reached out for an interview. They were nice with flexibility in offering to interview according to my availability. However, on the day of the interview it became apparent that they did not have a very good plan in place, with respect to the order of interviewing candidates. The person who had invited me wasn't present. Other employees were asked to fill in, who were very busy. There was a constant churn in the interview panel, in which employees would come, talk / ask questions for a few minutes, and leave in a rush due to issues with their running experiments. This sort of process is disrespectful to the potential candidate who has taken the time and effort to prepare thoroughly for the interview. Also, some of the "interviewers" are themselves very new to the organization, with less than 6 months of experience, and it is difficult to get a sense of the company from these panelists.
