Very general in terms of topics. Interviewed with the essentially the entire executive team (HR / Tech Ops / Regulatory / Finance / Medical / Legal / Project Management / CEO....) . Did not receive offer but found the company and its business plan very interesting.
My only recommendation to the company would be to improve how you manage notification of candidates after having them spend hours interviewing. After many interviews over the course of a number of weeks, it required an email and (after no reply) a subsequent phone call to Head of HR to learn the role was filled without even a thanks for applying. This could be greatly improved upon.
