Meteoric rise is both the strength and weakness of NICE.
Pros
NICE is a great company with some of the best people I ever worked with. They are smart, work to win and truly care about the survivability of the company. Many go above and beyond the call of duty to make sure this happens. Perhaps most importantly people are respectful and genuinely care about one another on a personal level. It is this level of commitment which has gotten the company to where it is today. Good products and solid market share.
Cons
NICE's success is also its downfall. Upper management is dysfunctional with some of the folks getting to positions which they should not be in, based on the success of the company. There is the "upper management" club which is downright rude and abusive to the aforementioned people who go above and beyond day after day. It is for this reason that there has been a large amount of turnover and there has been slippage strategically. It was very sad to watch good people go because of upper management. Equally sad was that the people who should be leaders have the worst behavior. Pay is relatively low, benefits are good. No work-life balance as management will call you routinely after hours or while you are on vacation with some fabricated fire drill.
