Don't just dive straight into whatever you're asked to do, take a bit of time to understand the department/division/company structure. Try to get a mentor assigned for the first six months, ideally someone from a similar role but NOT your department. Get them to help you navigate and understand the organisation/policies/procedures/key players. In a large company you can be hammered for not following procedure, if you are following procedure you are safe. This is my own advice to myself, after changing industry four years ago I'm moving to a new company but same industry next month. These are some of my biggest take aways after going in to recover from a everyone got hit by the metaphorical bus scenario with not hand over and little support. I'm probably a bit on the negative side but I think the advice holds up either way.
