Pros
With Five9, it's a hit-or-miss situation. Depending on the team you join and your professional goals, you may love or hate it. If you are not extremely ambitious and just want an okay place that earns you some cash, Five9 is a decent option. Bishop Ranch location is awesome, nice environment, whole foods nearby, food trucks a few times a week. Also, company has some nice events, like the annual ski day held at Kirkwood.
Cons
The company doesn't seem to do all that well on the market, that's a concern for the future and it also reflects potential internal issues that are not being resolved. Lack of competence and proper leadership in some teams and areas is a source of frustration. Also, the company is not very generous when it comes to promotions and yearly salary adjustments. The overall attitude towards employees sometimes falls short, especially in tough situations when someone has to leave the company.
