Pros
Some people are genuinely good, but almost always unhappy. You can't help feeling bad for them.
Cons
Buyer beware! There are only two types of reviews here: extremely bad reviews, and extremely good ones. That can only mean one of two possible realities: either CareDx is the greatest place to work, and there just happen to be dozens of misfits in all departments (in a small company of 200 people); or it's actually a bad place, with fake good reviews manufactured by HR. Which scenario is more like? You be the judge. Another piece of data, look on LI website and see how long is the average tenure of employees. There are MANY in sales, marketing, customer care, lab operations who did not last longer than 18 months (some quit in less than 6mons). Maybe these were the same misfits who couldn't figure out why CareDx is a 5-star company with the best culture? Maybe it's all their fault, and none of the company?
