Pros

pay is ok because of NH income tax thats it

Cons

STAY AWAY!! Unless you enjoy destroying your mental health. The worst managers I have ever dealt with. All they do is belittle you, overwork you, disrespect you, infantilize you, and never appreciate your work. They expect you to be a robot, stay in late for work, do a lot more than your job description but will never appreciate you. Management is completely childish, unprofessional, and deeply toxic. Managers demand that you constantly slave away after hours and go 'above and beyond' without an ounce of appreciation, but the exact second you show a shred of humanity or arrive one second late, they write you up out of petty spite. It is an insulting, hypocritical environment run by incompetent managers who treat grown adults like undisciplined children. The hours are 7pm-7am, very bad for your health and time. Furthermore, HR will never accommodate personal improvement education, most of the time they wont even answer you or give you an answer that wont help at all. Absolutely useless.

Pros

Lots to learn about producing API's via fermentation in bioreactors. Lots of room for career growth towards other departments and positions, from the business to the research. Good pay and lots of benefits are offered, such as dental, vision, and medical insurance; they also have a weight-loss program that I'm taking advantage of. Quality is prioritized, so there is no pressure to learn quickly, work faster, or meet quotas to do a good job. Teams are reliable, especially when learning the ropes; they'd be a part of the job I'd miss most if I leave.

Cons

Take careful consideration and be transparent with the supervisors if you're still exploring, as it's not an entry-level job that can hire and train new people at a fast pace all the time (I'm comparing this to retail and fast-food places, though). I live an hour away and work night shift, 7 pm to 7 am, thus the total amount of hours away from home is 14 hours. Please consider your mental endurance as well as your physical endurance for the night shift, as this job requires you to be on your feet, think critically, and can challenge one's work-home life balance.
