Pros
Friendly and talented co-workers. Can't think of anything else.
Cons
The CEO is very unprofessional. He has limited scientific knowledge but pretends otherwise. Never appreciates good work (I have never heard him say good things to anyone) but is always finding faults. The lab lacks good equipments and resources and you have to borrow from other labs in the building. Reaching work at 9:01am is considered being late and you will be lectured. He once made an employee cry and then blamed her for being unprofessional and shedding crocodile tears. He will not believe well documented (and even repeated by multiple people) results if they are unfavorable. It's next to impossible to have any intellectual conversation with him. He treats the senior Scientist as his personal assistant and expects him to do menial tasks that are not related to lab work. Pay is much lower than industry standards. The building has bugs and mold everywhere.
