Pros
Global is a great place to get your feet wet in the world of IP. They hire people straight out of college or grad school and give them training in a lot of patent basics. They are willing to sponsor non-citizens, which can be a big plus. My (peer) coworkers were fantastic to work with- smart, patient, and fun. Compensation and benefits are decent (not the greatest, but certainly not bad at all.) There is some flexibility with hours, and I was never asked to stay very late or to come in on weekends.
Cons
Turnover is very high, mostly because there are few opportunities for advancement within the company. A lot of people stay for a year or two and then move on. Vertical communication and direction from management higher than your immediate supervisor is non-existent. The projects can be extremely repetitive and mind-numbing at times. Staffing levels in my group were never adequate to handle the workload. Salaries and benefits have not been updated in years, and certain changes that were made years ago are not included in current offer letters and new employee information. Communication and social interaction between groups is non-existent, except when you awkwardly run into somebody on your way to the bathroom.
