Hi there,
You have two questions here!
Lack of Experience
1) Take on anything and everything you can. There are plenty of courses, academies, and internships (unpaid, part time) you can sign up for. Start your own business/website, build up skills, join groups/communities in leadership positions, etc.
2) "Fluff" your resume. There are ways to hide lack of experience and make a resume look a lot better/fuller. I'm happy to work with you on this. It's certainly a bit of an art!
Networking
a) Reach out to people in your network
b) Reach out to people once removed from your network
c) Reach out to people with a similar backgorund to you (i.e. same alma mater, same historically underrepresented demographic i.e. gender, orientation, ethnicity, etc., same career switch, etc.)
d) Tailor a message to them specifically both showing interest in them and their journey and demonstrating that you have done your research and could be a valuable hire
e) Play "tag" across calls you get so that you can work your way towards the company/office/role you want
f) Never directly ask for a referral, but "hint" at needing one (this is nuanced and important...happy to talk through wording)
