Pros

Not a single pro, this company is awful

Cons

- Leadership promotes their boys club buddies that severely lack leadership skills - The product sucks. It's nowhere near industry standard - The culture is HORRIBLE. Very much sink or swim, no support, zero engagement with other employees unless you suck up to them or are in the office - Mid Market "RVP" leaders are some of the worst Ive ever seen. If you dont go to them to appease their ego for every little thing, they will "manage" you out - SKO was the worst broke company efforts Ive ever seen. Shouldnt have had one, this company is embarrassing. The public speakers and corny jokes were the most cringe thing Ive ever witnessed, Ive never felt more demotivated in my life - Boys club culture to the fullest, if you dont stroke everyones ego, you're out Stay far away from this company. Go to a real CX/UC company. FIve9 is begging for acquisition and no one will take them. The system is old and ugly. Run from this org. Don't bother.

Pros

Any remaining positives are diminishing quarter by quarter.

Cons

Leadership claims “hope is not a strategy,” yet hope appears to be the strategy. There are no clear examples of new infrastructure initiatives that have undergone rigorous testing—or, in some cases, any testing at all. The prevailing approach feels like rolling the dice and dealing with the consequences later. Task assignments are driven by evident favoritism rather than qualifications, workload balance, or availability. This undermines both efficiency and morale and reinforces a culture in which outcomes depend more on proximity than on performance. Hope is not a strategy. At this point, stability isn't either.
