Pros
Location (Tarrytown). If you do not like living in the city but don't want to be far from it, this is a good location. Also has quiet towns near by. Very science driven with seminars from visiting professors/consultants Pay was okay (depending on where you lived) but supplemented by stock options (and the stocks did well eventually) Health insurance was decent Company had 401K matching program For a midsize company, we got to see some degree of how science drove some decisions in group meetings Not unheard of and not too difficult to transfer from one group to another within the company Overall friendly atmosphere. Did not feel heavily toxic (could have been in some other groups)
Cons
Group dynamics could greatly differ within the company and the degree of company culture was dictated by what a group head tolerated/allowed. Pay was not as competitive as some other companies. Depending on the group, one could work extended hours Evaluation was a sham (as with many places). Promotions seemed to work on a quota system. Doing something "well" for a year, meant you had to show "consistency" into the next year. This consistency was subject to evaluation the next year with or without quarterly/mid-year feedback.
