I highly recommend you do 3 things:
1) Apply to offices where you have relevant work/life experience (internships, jobs, studies, living, language, etc.). At least do this as a 2nd choice / backup
2) Ask for a referral where it makes sense - In general, you shouldn't directly ask for a referral (especially not from everyone). However, if you felt you made a particularly strong connection, it doesn't hurt to ask a few people where you think the odds are higher. Wording here is important...feel free to shoot me a message and we can wordsmith this a bit.
3) Network more and network better
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 hometown, 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) Leave a strong impression - i.e. don't ask "basic questions". Rather, demonstrate your ability/intelligence by asking smart questions, carrying a natural conversation, showing genuine interest, etc.
