I see. I might have said "Thanks for the reach out. What is the job you're offering?" It feels a little more collaborative and open and interested than "I'd prefer to not send anything until having a chat".

Having said that, I suspect it might not have made a difference. If you're really interested in them, see if you can find their job listings and apply. Or maybe this has sparked in you curiosity about other similar jobs so maybe search more widely. Good luck!
