Not the parent, but the US-based Financial Services company I work for also does a 3 month training scheme for their new graduate hires. Better yet, they brought all of their graduates worldwide out to the same place - so we've now got a worldwide network of people who started at the same time as us and that we've spent months with together.

Alas, due to cost (airfare and accommodation for everyone for 3 months adds up to a lot!) they've now scaled it down to just within each region rather than globally - so all of the NA graduates will train together, all the EMEA ones etc. Not quite globe-spanning as before, but still 3 months long and with people from other locations, just not all locations.
