Asking for the "Resume Push" (2021 SA) and Maintaining Networks

Hi everyone,

I understand there may be info on the topic but I'm asking how to keep connected with people in my network and eventually ask for the resume push (2021 SA).

Let's say I've talked to three people at a bank, should I keep contact with all of them or one? What if multiple conversations were really good? With that being said, what do I say when reaching out to them a month to two months after the call?

Also, if I do follow up for a virtual coffee chat/follow-up call, what if they don't reply? Should I follow up or is it appropriate to hit up another banker?

Finally, when asking for the resume 'push' (obviously indirectly), should I only hit up one banker per firm or multiple?
