I’ve talked to multiple C-level execs in my career.
There are many different leadership and communication styles but at that level you need to be succinct, direct, and know at least something about the business challenges they have.
A lot of technical employees want to jump right into technical problem solving - and sometimes that’s fine given context and audience or if you already have a relationship with the audience - but in my experience you need to understand their world and how what what you bring to the table is relating to the business and their direct care abouts.
