Pros
check out the fake generic positive five star reviews in May and June of 2016. This pretty much sums the situation at Myriad. They are willing to enter in fake review into Glassdoor to improve their image. Do you want to work for a company that is willing to do this? What does that ultimately say about them? Do you think they will treat you fairly once hired? Do you trust them to be honest on a review when they are willing to be dishonest on Glassdoor?
Cons
management cannot be trusted. HR is completely biased toward management and clueless in job requirements. management is also home grown so it's often that the guy that used to manage the network there ten years ago may be the VP now. do you really want to work for a company where the VP level is still making mistakes to learn the job and firing those that get caught in the crossfire?
