Pros
Great mission. Outside of the leadership layer, a diverse employee population well at least while I was there. (Generational, thought, age, sex and ethnicity compared to many other technology companies I have worked for.) Work that's quite cerebral. (Only if you're not in the HR department.)
Cons
Nothing negative about the company that acquired Medidata Solutions rather, a lot of the turmoil is a result of new leadership and the management layer they have been brought in to fill in for the fact that the Co-Founders have moved into different roles within the management layer of the acquiring company. No longer software product focused. Heading towards becoming simply a contract research organization. Or maybe some clone of the companies that the new management have come from. Obnoxious behavior by new leadership. Especially on the Software end of Medidata's practice. Certain leaders need Executive Coaching. Very smart people but they have no sense of self nor clue as to what they project to their employee base. Even if internally they don't have it in them to be humble, personable or empathetic they need to at least try to feign impeccability. Outsourcing technology. HR leadership is either the personal police force of leadership or they are there to rubber stamp any and all decisions. Can't blame them since they are protecting their jobs. Also, HR doesn't contribute to revenue so not much can be expected from a department that serves at the pleasure of leadership or department heads who actually make money for the company. Not saying this to offend anyone but this is simply a fact. You can do mental gymnastic to prove me wrong but show me the money (not savings but profits (new money)). Turnover (as a result of bad management even before The Great Resignation). Lack to resources for HR.
