Pros
In general, Genesys makes it a point to provide the best working benefits it can. This includes frequent communications from the executives, good benefits, fair salaries, consistent employee review process, etc. As with any company, an employee's experience is largely based on his/her direct manager and team; however, Genesys cultivates a culture of respect. From what I've seen, poor behavior is not tolerated. People are knowledgeable, helpful and driven to succeed. Genesys' solutions are very strong and having worked in tech for a long time, I can tell you it's always great to work for an industry leader.
Cons
Sometimes takes a long time to get things done; too many opinions and committees. That said, every company has its crazy. Just depends on what you want to tolerate.
