Three key ways:
1) Have a convincing / powerful resume
2) Have a strong cover letter
3) Network effectively!
In terms of networking effectively:
1) Check out the PrepLounge Q&As
2) Sign up with a session with a coach (I can teach you what you need to know in just 1 session)
3) Follow these immediate tips:
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)
