Need to do top-quality work - mediocre work will cause rework and more work than doing excellent work the first time
You don't get a blueprint - need to make your path and learn how to swim in the pool
Challenging/meaningful work sometimes leads to longer hours - if you are looking for something without responsibility to get the job done even if it means a longer day or longer week (or longer month) then this may not be it
Universe of knowledge is large - spend the first part of your career really learning the basics and the rest of your career continuing to build on that
Not a place for titles. If you are highly motivated by the role on your deskplate, this is not a good place to build a career. Titles are seldomly used even when they may exist for upper management.
Strong culture - (see above) - you'll either buy-in and like it, or you won't. Doesn't leave a lot in between.
