Pros
Worked at Yankee for three years. Great, intelligent, driven analysts and support staff.
Cons
Shockingly inept, narcissistic and vindictive "leader" shaped company culture with a policy of staff retention by litigation and threats. Attempt to leave and the MA "Non-Compete" dropped like a ton of bricks. Company driven to ruin through mismanagement, disastrous managerial hiring choices and general cluelessness on any strategic direction, compounded by throwing money at "consultants" who sucked the coffers dry. Idiotic PE firm backing this debacle let things slide until demise. 451 acquisition may have stemmed the rot, but only a handful of actual analysts left (have a look at the staff - most of the team is actually a separate data analytics firm in Colombia). Prognosis - terminal.
