Best client briefing questions

Hi recs! I have an interview with a RPO agency next week. This is such a great opportunity and I want to get back to this model of recruitment.

The interview will be a live assessment, which will be a mock client briefing and then boolean search session.

Besides the normal Logistic based questions, what are your best client briefing questions? Like the ones you feel make you stand out as a Recruiter?

I need to knock the socks off these people and I am wanting more depth, better than chatgpt suggested Qs.

Thanks
