some of this probably applied to teaching as well as general office environment so disregard if so:
- after you've spent enough time there to figure out who the most respected and highest ceiling people are in positions at least two levels above yours pick out the best candidate and ask them to mentor you. in the opening discussion find out how much time they could invest (like 1 hour every two weeks or a month or whatever) and set a meeting for those times and come prepared for that meeting with questions and seeking advice (even if you don't have anything you need come with open ended questions and let them talk). You can also ask to be involved in projects they are working on. you'll a) learn a lot and b) attach yourself to their coat tails to get a piece of their rise through the company.
- you'll eventually have a ton of time to goof off and message board and just waste away. doing some of that is good but use a lot of that time to develop yourself. get a designation, take a class, take on additional work, volunteer for projects, whatever. again, multiple things here, you'll a) learn a lot and b) make people see you have drive.
- ask a lot of questions. don't "fake it till you make it" because you'll take some black eyes. also it shows you are really paying attention. BUT, when you are told to do something do it to the best of your knowledge and THEN ask if you did it correctly. be a self starter and all that.
- agree on dress above requirements (but don't go nuts), agree on attending all after work stuff you are able to.
- if there is a society in the space your company is in join it and be relatively active in the society.
