Vantaggi
The people with whom you work are always a pro in my opinion. A laboratory position with this company should be seen for what it it: skills building to a better job or a temporary move to hold you over until a better opportunity opens.
Svantaggi
The division in which I worked (Upstream) left almost no personal time; between my hire date in June 2015 through Labor Day, I had 9 days off. Overtime was outrageous but expected by management. This may be a plus for some but I value my personal time much higher than what SGS was paying me to prioritize their needs. Vacation time would rarely be approved by management due to workload prioritization which led to the majority (~75%) of employee vacation time being lost (SGS doesn't compensate or roll over unused vacation time). Unacceptable!
