Hi there,
You need to network! I cannot emphasize this enough. Look get to know a few people in the office of your choice and find a way to get recommended for the role.
In terms of networking tactics:
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.
Hi - No one replied, I tried.
