Prime Healthcare Services Jr. Business Analyst interview questions

I had three rounds, everything happened in a span of 12 days (pretty fast). The final HR round went well but the final question was a little bit wierd because they were asking me what do I know about their department (revenue) (and there's no info online about anything about their department)

Received an email requesting an in-person interview in 2 days time. Received job description/information 24 hours before interview, received final confirmation of interview 2 hours before interview. In-person interview took place during COVID-19 (year 2020). Interviewers did not wear masks and told me multiple times it was ok to take mine off.
