Diatherix Laboratories interview questions

The hiring manager joined the call and immediately complained about how busy he was and how it was difficult to find time to do this (I was very flexible in terms of scheduling). He did not answer any of my questions directly and rambled to the point that neither of us were sure what he was talking about by the end of each answer. Ended the call by reiterating how busy he was and that it would take a while for me to hear back from him. Never heard back from him and did not follow up because I was no longer interested.

Standard non-technical interview process. Questions about experience and personality. Interview at the time was during the COVID-19 pandemic, so the interview was a group interview. I wore business casual and spoke with a member of the operations team.
