TL:DR By choosing operational management, full cima qualification, am i closing doors before opening them with regards to financial services (banking/investment)? & what exactly will i be doing anyways?!As of ~October 2016, i'll be starting my career as a Graduate Management Consultant at KPMG. My background is in science and law, and i'll be honest, part of me has absolutely no idea as to what to expect come October. Of course i've done extensive research and i'm interested, but like most advisory jobs, you don't know what it's going to be like until you've got the client. I'm not working in the city so i don't expect to be working the high profile cases, but my location is seeing clients move from the city to them due to HS2, who can guess where i am?! The other day i received an email to choose which sector i'd prefer to work within. "Operational Transformation", "People & Change" or "Financial Management". Although the email contained information on each, let's face it, it was a broad overview at best with no indication of actual day to day work.Unfortunately my location meant financial management was a no go, so my first choice was operational management followed by people and change. So far we aren't guaranteed to get our first preference as it "depends on the businesses needs", but i feel confident that i stood out during the application process and hopefully will land my first preference.I'd just like to know as to whether or not i'll be closing doors before i even open them? Will my chosen sector give me broad experience for both progression and into industry, can i go into finance later in life? What are my opportunities for alternative careers should i decide i want a change?I apologise for the many questions and lengthy post! Also, any tips for someone just about to dip their toes into the management consultancy industry (particularly within the big 4) would be very appreciated!
