Kontras
This firm has a real problem with innovation. They need a few more trailblazers. Many managers are afraid to be the ones that rock the boat and lead change. Be cafeful on the manager that you come in under. Some managers are just trying to lay low and people under them never get anywhere. Don't let them lead you to believe that a Senior Associate has any authority. You don't really earn respect unless you make Principal so if you have 10 years or more experience, negotiate a Principal grade upon hire because depending on the manager, it may take you years to reach Principal status. And there are lots of Principals...many of which don't deserve the title so don't let them act like Principal is a big deal. There are sales people that are hired in as Principals.
