Where am I going wrong?

Hi Monkeys. First of all, sorry for the lengthy post but I’m hoping by giving you guys all the info you can tell me where I’m going wrong.

My Story:
I’m a post grad student in the UK doing an MSF. I studied accountancy at undergrad at a top 20 university over here. I spent the summer after undergrad doing an internship in a MM PE firm and loved it so started learning as much as I could about the different career paths etc. after a bit of research decided ER was more my thing since I find public markets fascinating. Started networking like mad while working in the accounts office at the family business but to no avail. Decided my CV needed some beefing up so applied and was accepted to the MSF, which I started 12 months after finishing undergrad, having worked in the family business in the interim. The business school I’m at is top 5 and has a great reputation.

My problem:
Getting a job. More specifically networking into a job. I’ve been networking pretty consistently over the course of my MSF but somewhere along the line I’m doing something wrong since I end up losing touch with most people I contact. I’m trying to land something in London or New York (NYC is the dream but London is closer to home) So there’s pretty much two different scenarios, one for London and one for NYC. I have acted these scenarios out multiple times now with different people and don’t know where I’m going wrong.

Scenario 1 (London):
I send out cold email asking for advice on how to break into ER etc. a couple of emails back and forth, I arrange to meet them for a coffee and a chat. Normally it goes pretty well, I’ve always been pretty good at talking so conversation typically flows well and I feel like I make a good impression. I always get great advice and have found that in general people are really willing to help and offer to put me in contact with someone else I should talk to/ would be happy to pass my CV on to someone. I follow up after meeting thanking them again for their time and attaching my CV, saying something like “ thanks again etc. if there is anyone you think might be interested in my CV feel free to pass it along”. Often I get a reply saying it was good to talk and they’ll let me know if anything pops up. After this though, 9 times out of 10 they don’t get back to me. I follow up a few days later and again no reply. I assume they have decided they’ve had enough of me and move on to the next one.

Scenario 2 (NYC):

Scenario 2 goes pretty much exactly the same as scenario 1 but obviously I can’t meet in person so rather than meet for a coffee, we talk on the phone. Again, the people I speak to are easy to get along with and happy to help me out. Similarly though, after an email or two, I lose touch.

Is it just a case of being more persistent with these guys? I feel like 2 or 3 unanswered emails is pretty much a ‘leave me alone’.

Thanks in advance.
