I called back and a man said I had expressed interest in a job online and a HR company wanted to see if I was still interested, I said yes and he asked if it was ok to release my number to the HR team, I said yes, and they thanked me and hung up so it was a bit weird
Honestly not sure if legit or a scam, will follow up if I find out more

I called back number (02) 9136 1640 reached voice mail but did not say for what company.
