Many of the staff members are friendly, easy going, and are great to work with. Let me be clear, this does not include management.
Cons
Quantum is a underpaid, egotistical, misogyny nightmare. HR issues get swept under the rug, employees who don't do their job are praised and promoted, but the employees who do all the work and clean up after everyone are talked down to, under appreciated, underpaid, and left to the wolves.
