Pros
Quest truly strives for a diverse workplace. Being a Medicare payee, Quest also has strong compliance governance and lives it. Quest is patient and provider driven without a doubt. The amount of care the Quest support team takes to resolve and solve problems is exemplary. Quest has continually made improvements in employee education and a more robust performance management system. Recent improvements include opportunities to take time off as needed with manager approval and a number of positions allow some work-from home, improving work/life balance. Many talented people with great ideas working within a huge operation can make a difference and are empowered to do so.
Cons
In some segments of the Quest organization, specifically IT from my experience but certainly others, the turnover for senior leadership is very high. Old but good ideas are often quashed by new leadership. then to be revived again by the next leader. The problem is there is generally a short-sighted elimination of essential employees between such change of hands in leadership and the hard work done prior to reinvigorated ideas is lost as those employees and systems are turned over. It feels like Groundhog Day sometimes, especially being a long-term employee that went through 6-7 major reorganizations. The result is that Quest does not adjust well to new technology or set a trend, even though they have enormous influence and information to leverage. With that, a sense of paranoia about job security can accumulate if you've been with Quest for a while.
