Pros

Overall decent compensation package, work from home opportunities, intelligent coworkers. That is it. Everything else a con.

Cons

I literally feel like I have PTSD from this job. Every day (including weekends) I worked 10+ hours and was not infrequently in tears, for the first time in my career. I am not dramatic or inefficient so it was quite a shock to me coming from previous companies. Work life balance is nonexistant. You have to put in ridiculous hours and the company as a whole was tragically under staffed making it impossible to do your job adequately. Little useful training and clunky old systems that are frustrating to use are the norm. Very rigid corporate structure, email overload, annoying time tracking etc. Parexel will take on any study to the detriment of its employees, and the studies keep piling on.

Incompetent and nasty

Pros

Flexible work-from-home policy, that is all

Cons

Never in my life have I worked with a more incompetent and, quite frankly, nasty group of people. You'll be lied to during the hiring process and then be met with resistance and open hostility any time you attempt to do the job you were hired to do (because doing your job successfully could potentially hurt someone's feelings). A clueless and disrespectful executive team and a horrible HR department work together to reward incompetent managers with promotions while driving away or laying off anyone with intelligence and talent. There is no job security here where frequent layoffs are the norm. I advise anyone reading these reviews to scroll back a few pages where it's a steady stream of one negative review after another, then suddenly in September the positive five-star reviews began flooding in. These are clearly fake reviews being posted by management/HR.
