Minpunten
Never heard more nonsensical topics during meetings; people sharing their sexual preferences, flaunting overly dramatic personal lifestyle decisions, diversity to the point of failure, etc. Hearing the term "white guilt" in a professional setting was, well, pretty unprofessional.
Stack ranking for performance reviews is a mess. Someone has to have an "F" regardless of their performance because that is what their line of business is allotted. Be prepared to be held responsible for actions any Sr Leadership would just sweep under the rug under their own circumstances.
If a manager doesn't like you, regardless of your productivity, you're toast unless you're able to find another LoB to support. HR / AR are just a check in the box and will most likely point you from one to the other and back again without resolving any issues.
You'll find yourself curious as to what leadership does as they continue to scrape managerial responsibilities from their plate, to yours.
Last but certainly not least; you may find yourself working hard on a project; nights and weekends, just in case that work life balance is feeling a little too perfect. Fret not, someone will surely assist in taking credit for the hard work you've put in.
I'm sure none of these things will happen to you, though.
Best of luck!
