After a call with the recruiter, interviewed with the Chief Business Officer.
The CBO's thinking seemed to be narrow minded because the senior team (CEO and CBO) have limited experience beyond Rigel. There was no gender diversity in the department (all male). The CBO didn't seem to be that great, i.e. not super experienced, but arrogant about his position / title, yet he expected a lot of experience from the candidate. He openly stated there would be no opportunity to work on the deals, i.e. no career development. He couldn't clarify exactly how deals would be done with Rigel's very limited cash on hand; cash position has stagnated despite recent launches, a red flag.
