Anyone been approached by or have worked with "Health First Group"?

Hi,

I am currently based in Singapore. I was approached on LinkedIn by a HR lady from Health First Group in Australia.
I have a first Google Meet with her coming up but would like to know as much info as I can beforehand.

Wondering if anyone has worked with this healthcare provider group before or know any reviews/feedback from those who have worked there before?
This is their website: Home - Health First Group
Seems to be quite established, although not sure how they expanded with many clinics all around Australia in a short time (since 2016).

Appreciate any info or even tips on what questions to ask them. (it'll also be my first overseas-based interview)

Cheers!
