Pros

Always work to do, PTO and Healthcare if you need it. Mostly everyone is easy to work with and nice

Cons

Quest (PhenoPath) used to be a great company to work for, but then the corporate level employees starting making bad financial decisions. Because of negative finances, jobs were cut, but the work kept increasing with no end in site and no support from management.
