1. If you are part of specific orgs, such as Dealertrack, Accelerate, or Dealer.com, expect to have a re-org roughly every 6 months. Your directors and leadership will likely realign. This makes it difficult to ever advance since you have to prove yourself again to whoever your new boss is. I received one promotion in the last three years I was there, and only because my new boss had worked with me previously on another project. This also causes challenges with actually completing projects you previously gained approval for since the new leadership will have new priorities. Your plans will likely pivot every three to six months, and when it happens, you will be expected to scramble to size and deliver whatever the new shiny idea is. This will happen sometime after you have completed quarterly planning, so you will lose valuable time trying to investigate, scope, and determine delivery of whatever new thing they came up with
2. You have a decent probability of seeing people in your business unit either terminated or offered demotions roughly every 6 months. It isn't based on work ethic or contributions. It doesn't matter how long you have been there. If you have been offered a demotion, it will likely be more responsibilities for less pay
3. Leadership above the director level typically has a "what makes me look good" mentality. They can be aggressive, harsh, and criticizing if your aren't someone who supports their agenda (which again, changes every 6 months). They tend to hire and promote individuals who talk a good game, but don't actually produce quality, valuable products.
4. Like every other company I have worked at, don't expect to go past your "pilot" or "MVP" product release because they are already planning the next crazy thing they think might advance their own personal agenda
5. You will bear continual underlying stress about whether you will have a job tomorrow, especially in the January and June timeframes when the axe tends to fall (sometimes a small one in the fall as well)
