Pros
You'll learn how important it is to know what drives someone to reach their goals, especially your closest colleagues. That is something I've taken with me as I've moved on from TEK.
Cons
I worked in an office where the politics and turnover were high, HR was nowhere to be found, and poor leadership. Anyone higher than a recruiter wanted nothing to do with you unless you were going to make them money, so don't expect too much "relationship building" until that has happened. Someone left the company every two weeks which looked bad internally and externally. Consultants/contractors had some new junior recruiter calling them every month to have the same conversation over and over again because the last recruiter quit. There were many, many non-HR-friendly conversations happening daily, but no one was around to censor anything. Leadership doesn't appreciate any type of strategic thinking or creativity. "Hard work" was only found in a high number of dials and face time.
